Sentry Crash Report:

Description James Barbot (Jr) 2021-10-20 03:11:10 UTC 
Application: kstars (3.5.6 Beta)

Qt Version: 5.12.8
Frameworks Version: 5.68.0
Operating System: Linux 5.11.0-38-generic x86_64
Windowing system: X11
Distribution: Ubuntu 20.04.3 LTS

-- Information about the crash:
Was running Kstars -> Ekos -> Scheduler...

Had it targeted on a galaxy, it had gone through all the steps just fine (start-up, goto, focus, align, guide, imaging, etc.) and was on the 2nd image and just froze.
And then crashed after a few minutes of being frozen.

Wasn't doing anything unusual at the time, just using it as usual...

Did a full sytesm update and upgrade (apt upgrade) earlier and noticed that I received a new version of the ubuntu kernel, but other than that, business as usual.

-- Backtrace:
Application: KStars (kstars), signal: Segmentation fault
Using host libthread_db library "/lib/x86_64-linux-gnu/libthread_db.so.1".
