Very kind, thank you.

It is old, an K6-2 450mhz. I bought it and the mobo new (P5A Asus) new years ago. The RAM is of various origins, but I get no beeps as it boots. Not that would help much the manual doesn't even describe what various beeps mean if it were to. Its not modern, but 2 evenings ago I got a K6 233mhz box running just fine. Slow, but if you had nothing else you definately could get some actual work done with it running wheezy.

It happens a lot, but no single app is gaurenteed to seg fault.

Here are some examples from the syslog:

I'll do this tonight.

It mostly seems random, one thing that seems consistant is adding apps to the LXDE launcher on the panel. If you do 3 or 4 in row it pushes it over the edge. I think the first series of errors above is me doing just that.

Thanks. Hope you don't mind the direct reply + cc, let me know what is preferred.
