-- Information about the crash:
- What I was doing when the application crashed:

I was testing kmail 2 and akonadi/nepomuk were hogging resources making the computer practically unusable, I killed the mysqld process to try and escape and at some point plasma crashed with the following backtrace. Not reproducible I'm afraid.

Cheers
M.

The crash can be reproduced some of the time.
