-- Information about the crash:
- What I was doing when the application crashed:
Hi, my plasma gone mad, it started to show me some notifications with just "File:" in it, 1 for 5sec. and the number in the notification circle in panel stil grew up. Also plasma was freezed for a while when showed that notification.
Then I wanted to restart my Kubuntu, but plasma definitely crashed.
I will add an screenshot as attachment.

The crash can be reproduced some of the time.
