Bug 398841

Application: kstars (2.9.8)

Qt Version: 5.9.5
Frameworks Version: 5.44.0
Operating System: Linux 4.15.0-34-generic x86_64
Distribution: Ubuntu 18.04.1 LTS

-- Information about the crash:
I configured a sequence of flats as before, in the calibration section, I chose ADU and adjusted its level. Once the sequence was configured, I wanted to launch it. A picture was taken, then nothing. No automatic exposure adjustment with successive images. In the sequence queue, the flat sequence is indicated "idle". I click to restart the sequence, kstars crashed and return to the desktop

The crash can be reproduced every time.

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