Application: kspaceduel (2.1)

Qt Version: 5.11.2
Frameworks Version: 5.53.0
Operating System: Linux 4.15.0-43-generic x86_64
Distribution: KDE neon User Edition 5.14

-- Information about the crash:
- What I was doing when the application crashed:

Playing the game like normal, as I had for about 50 rounds across several different sessions without a crash.
No idea if it's related but I had picked up a green circle powerup thing less than half a second before the game crashed.

-- Backtrace:
Application: KSpaceDuel (kspaceduel), signal: Segmentation fault
