Sentry Crash Report:

Description Akarsh Simha 2020-05-23 09:17:09 UTC 
Application: kstars (3.4.2)

Qt Version: 5.13.2
Frameworks Version: 5.64.0
Operating System: Linux 5.3.11-arch1-1 x86_64
Distribution: Arch Linux

-- Information about the crash:
I had set up CCD Simulator and Telescope Simulator connected to a running INDI Server. I have no filter wheel (or filter wheel simulator). I tried to change the exposure type to Luminance, because I did not see any stars and thought this might be a problem. Then when I hit capture, KStars crashed.

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