total crash

[onli]

First of all I want to thank you, the linux-client works very well and I thougt until yesterday that it is absolutely stable.
But yesterday, my whole system crashed while playing regnum, the only thing I could do was to press the reset-button. After the reboot I tried to check my logfiles and it crashed again - the /etc/var/syslog had a size of 1.6 gb!
I had to erase the file, and now I'm wondering how this could happen
The syslog.0 is filled with these entries:

localhost kernel: [17191249.492000] [fglrx:firegl_rmmap] *ERROR* map 0xdcb7c2f0 stif0 still in use (map_count=1)
localhost kernel:[17191249.492000] [fglrx:firegl_free_buffer_queue] *ERROR* buffer qeue 0xdcb7c2e0 still mapped

For one second both entries are more than 100 times written down.

I think these entries are caused by the rolauncher, but I'm not totally sure. Another Player using an ati card had the same entries in his syslog...
Is this a known bug? Is it really caused by rolauncher? Is it a memory-leak (the only hint I found with google)?

My System:
Ubuntu 6.06
Radeon 9800
OpenGL version string: 2.0.5814 (8.25.18) (fglrx taken from the repository)
