Application: kstars (3.2.0)

Qt Version: 5.9.5
Frameworks Version: 5.44.0
Operating System: Linux 4.15.0-47-generic x86_64
Distribution: Ubuntu 18.04.2 LTS

-- Information about the crash:
- What I was doing when the application crashed: clicked on the start button in ekos - 100% of the time.  I'm on kubuntu and tried doing a purge then install and this still gives the same error.  I also repeated this but removed the .indi folder first.

The crash can be reproduced every time.

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