The game doesn't start

[LeBarjack]

Here are some informations about my system:
linux kernel 2.6.30 / 64bit system
Athlon(tm) 64 X2 Dual Core
Nvidia card with drivers 185.18.31

The rolauncher works correctly. I can log in and launch the game. There is some sort of verification routine which also seems to work ok. Then, the game hangs on a small unresponsive gray window.

Here is a trace of the main process:
strace -p 3048
Process 3048 attached - interrupt to quit
futex(0xdb6ed4, FUTEX_WAIT_PRIVATE, 1, NULL
^C <unfinished ...>
Process 3048 detached

And for other threads:
strace -p 3048
