Hi,

I just installed these additional packages. As I had to close the gdb 
window anyway, I'll wait for the next crash. Actually there was another 
crash (kindof) this afternoon, before I got round to installing the 
debuginfo packages. The crashes seem to come in pairs, for whatever 
reason. In any case, this crash left gdb spinning one of my two CPUs at 
full speed before it printed any debug information. I pulled the plug on 
the gdb process after like 20 min as it did not seem to lead anywhere.

regards,
Markus
