KNotification calls from fits viewer crash kstars was created by Derek

It happens intermittently, except for tonight where it was happening constantly and after approx 2hours I gave up using the observatory with nothing captured.

<strong>My setup</strong>
I'm using an ASI 120mm for guiding, plugged directly into a USB2 port on the PC.
The PC is running both Indi server and Kstars. I start the indi server locally by clicking the start indi button in EKOS.
So everything is running on the same machine....

<strong>The Problem</strong>
Once I start using the ASI camera, It works fine for a duration, usually enough to get calibration done and start guiding but then everything dies. Kstars just disappears. No warning or alerts from KDE. Sometimes it dies during calibration too....
INDI server is still running because when I restart kstars and click start indi it asks if I want to kill the already running instance, I click yes and try all over again..... Same result about 10 times tonight.
I'm 99% sure its the ASI camera. I've tried all the other EKOS modules tonight, align, focus, capture and they never cause a crash. However once I start using the guide module and interacting with the ASI camera I have this problem...

I'm looking for help to debug this so I can get some more information as to the cause.
Anyone have any ideas? Nothing appearing in the indi logs. Kstars just vanishes. Are there any other logs I could check?
Maybe I should start indi-server from the command line and then start kstars? Would that help?

Any help would be great.
Thanks!!
Derek

Install kstars-bleeding-dbg package then run KStars via gdb:

sudo apt-get install kstars-bleeding-dbg
gdb kstars
run

If it crashes, type in bt to get the backtrace and post it here.

OK I have some update on this. The weather was bad so I only started some equipment with the roof closed. I didnt get the same 'vanish' crash behaviour but it did crash (got notification from kde).
Actually now I'm starting to think its something in the fits-viewer app. Or maybe some weird interaction with VNC maybe... I'm accessing the system using x11vnc.

I have 2 stack traces. The first is using the ASI cam in the capture module to capture a series of 1second subs.
The second is using the CCD simulator to do the same thing..
I noticed 'FITSView::loadFITS' is common in both traces.

This reminds me I have noticed kstars to crash before when I use the fits viewer to open a file. Nobody else seems to have this problem so it could be something on my system or some vnc interaction.

The crash appears to happen in KNotification calls. I tried replicating it (Using ASI on Rpi) and couldn't get any crash on Ekos VM. So I'm not really sure how to go on about your issue, how about checking if you get the same problem using TeamViewer?

Thanks Jasem,
I used the PC in the observatory today directly (monitor and keyboard) and can replicate the issue without vnc in the mix.
So its something weird that I have installed or something. I'm able to replicate now with the CCD simulator too so the title of this thread is now inaccurate.
I've taken the PC home to where I have good internet access and as soon as I sort it out I'll update the tile and post the solution so it might help someone else.

I have 'fixed' the problem by upgrading the OS to kubuntu 15.10.
I have no idea what I did to the system to cause the original issue but hope this might help someone.
Updated this thread title to be more accurate also.
