Regnum, Mesa, 9.10

[Anpu]

Hi,
while I was able to run Regnum in 9.04, I am not able to do so in 9.10.
I am using ATI Radeon 9250, Mesa, and I think I did everything I did on 9.04 to make it work. But, on Kubuntu 9.10, game is simply crashing when starting autodetect, or when clicking and entering on server from a list.

Crashlog:

Am I missing something?
