Bug 293404

Application: konquest (2.1)
KDE Platform Version: 4.8.00 (4.8.0
Qt Version: 4.7.4
Operating System: Linux 3.0.0-15-generic x86_64
Distribution: Ubuntu 11.10

-- Information about the crash:
- What I was doing when the application crashed:
I was attetempting to clicking on the minimap but instead clickded slightly off of it. This results in m_map->sector(m_selection) returning null because m_selection is out of range. MiniMapView::mousePressEvent then calls hasPlanet on the null pointer and crashes.

The crash can be reproduced every time.

-- Backtrace:
Application: Konquest (konquest), signal: Segmentation fault
