Bug 394725

Application: kstars (2.9.5)

Qt Version: 5.7.1
Frameworks Version: 5.28.0
Operating System: Linux 4.9.0-6-amd64 x86_64
Distribution: Debian GNU/Linux 9.4 (stretch)

-- Information about the crash:
- What I was doing when the application crashed:
I launched a preview of the first sequence. After this was fine, I wanted to start the flat sequence. Surprisingly, the last entry had already started and it was not able to interrupt normally (button did not show running). After several clicks, it stopped. I deleted the last two entries and as I added a new one, kstars crashed (at least that's how I remember it).

The crash does not seem to be reproducible.

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