Subject: I just got got another Oops

Greetings all;

This is the 2nd or 3rd one of these I've seen.

This one may have a better set of clues as it occured about 1 second

And it was accompanied by some sort of an alert mechanism in F10 that said 
'KDE Write Daemon' in a series of 22 stacked vertically boxes, and duplicated
