Application: katomic (4.0)
 (Compiled from sources)
Qt Version: 5.6.1
Frameworks Version: 5.24.0
Operating System: Linux 4.7.0-gentoo x86_64
Distribution (Platform): Gentoo Packages

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

Pressing Shift-Tab while playing the game causes it to crash immediately. The expected behavior is for it to cycle through the moveable atoms in reverse order to how Tab cycles through them.

The crash can be reproduced every time.

-- Backtrace:
Application: KAtomic (katomic), signal: Segmentation fault
Using host libthread_db library "/lib64/libthread_db.so.1".
