[Merkaartor] Segmentation fault on file -> print

[Manuel Reimer]

Hello,

I downloaded a small piece of map and tried to print this out (File -> 
Print). Merkaartor crashed.... :-(

Why does Merkaartor have *that* much segmentation fault bugs? Is it 
really such difficult to write software with Qt?
