I am trying to bring a new to me Canon EOS M50 online for kstars.
The EKOS configuration is: Canon DSLR, telescope simulator
I have filled in sensor settings. Attempts to capture an inage results in:

Segmentation fault (core dumped)

I am using the Canon DSLR drver. Should it be the GPHOTO driver instead?

Additional information. From a timing perspective the seg-fault appears to occur when the image would be being downloaded. That is the exposure was 1 second. The seg fault occurs about 3 seconds after the take photo button was pressed.
Additionally, I reviewed all the logs and the defTextVector with no valid members error is reported in all of them, even those were no seg fault occured. I do not believe it is pertenant.

Canon driver is fine. If on Linux, try to run the driver via Ekos Debugger to get the crash backtrace.

Thank you. I am running Linux. I enabled the debugger repository and installed ekosdebugger and restarted kstars. I did not see any option to buttons to enable it. Can you point me to the path to enable the debugge?
Thanks Dan

I found it. It is a separate executible, I am starting it now.

This is the trace:

In the INDI control panel, do you see ISO list in image settings? It looks as if they're missing which shouldn't happen in any GPhoto based driver.

No. The ISO box is in the INDI Image window. It is a drop down. I have tried setting ti to both auto and 800. Conversly that button does not appear to be onnected to the EKOS camera window. In that window the ISO box is null and the gain window active. There appears to be a disconnect between INDI and EDOS.
Additionally in the EKOS camera window:
The camera field is null and cannot be modidied
The Format field is null and cannot be modified.
The Size Width and Height fields are limited to 2 charactors, i.e. values of 99 or less.
In the Sequence Queue at the bottom the left Capture box is active and the middle Repeat box active. However the Live box is crossed out and inactive.
Additionally in Indy in the Camera section there appears to be a disconnect between the General Info screen and the other screen. In the General Info screen the driver is GPhoto CCD an din the other field the 'camera' is a Canon EOS M50.
Thanks again, Dan

Additional Information:
Just for comparison I disconnected the M50 and reconnected the Rebel 1300D. It came up and populated normally and worked normally. All the fields above were populated correctly.

What is most likely happening is that the gphoto driver is not detecting required widgets in the camera. Is it in Manual/BULB mode?

Good morning. Yes the camera is in manual bulb mode.
Additionally there seems to be a cross reaction between the camera and the mount. Substituting the 1300D everything works as expected. However the M50 config interacts with the mount. The mount is 'idle' and nothing I can do removes it from idle. I have 2 configs, one is EQMOD_1300D and the other EQMOD_M50.
As a note INDI recognizes the M50, pulls the serial number, etc. There is nothing in INDI that indicates the M50 in not being recognized. Is there a way to directly cause INDI to capture an image?
