-- Information about the crash:
- Unusual behavior I noticed:
When add or pop up open in new windows, and i'm too lazy to open them to close with the "close" buton, I right click on the new open ads windows, close. And then plasma crash.

The crash can be reproduced some of the time.

-- Backtrace:
