Description Peter Tijerina 2025-03-29 20:07:17 UTC

Application: kstars (3.7.5 Stable)

Qt Version: 5.15.3
Frameworks Version: 5.92.0
Operating System: Linux 5.15.0-135-generic x86_64
Windowing System: X11
Distribution: Ubuntu 22.04.5 LTS
DrKonqi: 5.24.5 [KCrashBackend]

-- Information about the crash:
- What I was doing when the application crashed:
I configured EKOS to capture 20 flats and 20 darks. For the flats, I have a DeepSkyDad FP1 flip flap. EKOS normally knows to turn on the panel light and begin calibrating to capture flats at ~30000 ADU. I used the Flats wizard/tool and also the DarkFlats tool to generate the jobs, then run the jobs. But upon capturing the first Flat, KStars crashes.

The crash can be reproduced every time.

-- Backtrace:
Application: KStars (kstars), signal: Segmentation fault
