-- Information about the crash:
Plasma crashes when the message bar displays a list of pop-up notifications numbering more than 10, and the notifications begin to list themselves along the side of the page in the expanded form.

Since there is no "clear all" button, the list must be expanded to clear the notifications from the message bar...

 -- Backtrace:
Application: Plasma Workspace (kdeinit4), signal: Segmentation fault
The current source language is "auto; currently c".
