crash - should I upload the dump?

[Pierre Abbat <phma@xxxxxxxxxxxxx>]

I was copying something from a webpage to a document in Kate and the computer 
froze, then showed me the console saying that X could not be restarted. I 
killed kdm and logged in again. While all the windows were coming up, the 
computer turned itself off. I rebooted and found a dump numbered 12. Here are 
the tracebacks and some other info:
