Bug 306931

Application: palapeli (1.2)
KDE Platform Version: 4.8.5 (4.8.5)
Qt Version: 4.8.1
Operating System: Linux 3.2.0-31-generic x86_64
Distribution: Ubuntu 12.04.1 LTS

-- Information about the crash:
- What I was doing when the application crashed:
Piling a number of pieces one on top of the other, then with the frame moving on top of the pile to autoconnect pieces it started to crash.

The crash can be reproduced some of the time.

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