Ok fixed it without reinstalling, much nicer. So here is the output you requested. I guess this means it indeed is a gphoto issue?:

That's what I was looking for, I think there's something wrong with gphoto, probably it's the exposure parsing routine.
Apparently the "bulb" exposure doesn't seem to be found, sometimes I had that on my camera too, not even sure how I did resolve it.
I'm not sure, since I didn't write that part, but if you can recompile the indi 3rdparty drivers you might try to apply the attached patch, recompile, and see what's there in the exposures in the same log I told you earlier.
I want to rewrite parts of that driver to give it a more "modern" shape, making it also easier to track similar issues.

A few hints about "best pratices" on recompiling packages (both gphoto and indi):
What I usually do is to install the recompiled packages in an isolated directory on filesystem (usually /opt/<package-name>).
You can achieve this using
./configure --prefix=/opt/gphoto2
for gphoto, and with
cmake .. -DCMAKE_INSTALL_PREFIX=/opt/indi-svn
for indi and indi-3rdparty.
Then, when running applications (for instance, indiserver), export the following variables:
export LD_LIBRARY_PATH=/opt/<package-name>/lib:$LD_LIBRARY_PATH
export PATH=/opt/<package-name>/bin:$PATH
indiserver <usual-command-options>

I know it might be a bit tricky to do all this, unfortunately I don't have a 6D available to test all this, maybe I'll try to rewrite the driver as soon as possible though, adding myself the debug lines.

Thanks
Marco

I would love to recompile it but I'm afraid I don't have any experience with it on Linux. :( So I follow your suggestions, but could you maybe give me a slightly more step-by-step instruction? For instance I would need the source to indi_Gphoto I guess?

Ok, downloading the libgphoto source, 2.5.4 which is what is used on my pi and trying to apply the patch (which I just found out how to do). ;)

... but that however didn't quite work as planned. I think my installation is not setup properly for this, sorry.

I'll try a compilation within a few days again on gphoto itself, bit busy at the moment.

Btw, is there an alternative program I could use in the mean time? I know some indi clients but I guess they all use this driver right?

Hello again,
Very busy days, sorry... I hope I'll be able to help you more next week.
Unfortunately there aren't many other similar applications around, and yes, the other INDI clients still use that driver.
I really hope can work on it, I would need that too :-P

I used the driver to take 60+ seconds exposures today under Kubuntu on desktop linux without any issues.

No problem GoLinux, I'm glad you take the extra trouble anyway. It actually set a bit of fire on my old programming skills, I realize for these types of software, programming would be very handy. :) I'll try again this weekend, I do hope I can get it to work normally again as I don't wanna waste those starry nights.

@knro; did you test it with a 6D as well? Can you post the version of gphoto you now use for lib-gphoto? I realized I have 2.5.4, while that would be a version from 2014.. at least if I look at the gphoto repository which is at 2.5.9. Interestingly I now use the exact (well almost apparently) setup as you, kubuntu and Jessie on the Pi.

Oops. Looking more closely at sources of libindi etc. Go subversion! ;) I know about all of this, but never used it, so it's slow but I hope to be getting there.

Ok, I'm veeeeery close now. I managed to patch indi_gphoto_ccd, copy it to /opt/indi-svn and then started with indiserver -v /opt/indi-svn/indi_gphoto_ccd that seems to work, but I'm not getting that line you have in the patch file printed on the console. I checked it by hand and it should do it, as it is in the source. I didn't use those paths you mentioned as I just have the indi_gphoto source in /opt/gphoto-test/ and built and made it there. I don't see any /lib or /bin directories so I guess I'm missing something still.

So I managed to find a location in which output is generated (in the find_bulb_exposure routine). I inserted the line;
gp_dprintf("Choice: %s",gphoto->exposure[i]
within the for-loop. It generated this output, which I guess is wrong still, but if you could hint me to what I might have wrong, please do;

2016-01-16T17:04:39: Driver /opt/indi-svn/indi_gphoto_ccd: Exposure started

If I'm reading the code correctly, this find_bulb_exposure routine created a gphoto driver and widget instance and then starts looking for the choice that was returned by the parse_shutterspeed function. There I see a return value of NULL if the count (argument in the function) is <= 0, which apparently is the case. This count of <=0 seems a result of gphoto->exposure_widget->choice_cnt

edit: I just had a look at this choice_cnt value and that's 52. Mmm

edit2: One thing I didn't mention btw, I did have my camera modified to full spectrum in between, shouldn't influence this stuff should it? Seems it functions normally.

edit3: And it does function, I tested the camera now with BYEOS and that works. Camera set to manual mode and when capture starts in BYEOS, the camera display says bulb. So it's definitely a driver issue.
