Hi Martin,

Here is a fresh bug report (for initial report please see 
http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=482336)

I thought that it is caused by insufficient VRAM... swap space is quite
large... so shouldn't be... in any case -- please see below and the url
above

Thanks in advance for resolving it
