If i open the gb.map example and, at any time, do a quick scroll (this is,
a fast rotation of the mouse wheel to zoom in) gbx3 crashes. Here is the
output from gdb:

I can "sort" of reproduce them (i always get a crash when i scroll) but it
depends on that i do before it. If i move the map around a bit i get a
different crash than if i directly scroll.
I'm using a fully updated Archlinux x64 system.
If you need more debug info please let me know!
