Recent crashing

[Valour]

I'm crashing over and over, and just getting this in backtrace:

libs/libcore_client.so(_ZN10ClientBase14save_backtraceE v+0x79) [0xb7d27089]
libs/libcore_client.so(_ZN10ClientBase12client_crashEi+ 0x1b) [0xb7d2773b]
[0xb7f04420]
[0xb11d00c8]

Using ubuntu hardy 8.10, with intel 945 graphics card.

I play in 800x600x16 resolution and when the client crashes, my resolution changes to that or Regnums.

Help much appreciated!
