-- Information about the crash:
Plasmashell randomly crashes and restarts after hovering some icons in the Icons-Only Task Manager. This happens seemingly at random, hovering or clicking icons may or may not cause the crash, it will sometimes crash several times in a row, then remain without crashes for hours or days.
May be relevant that Chrome browser is open with many tabs and windows, and the Plasma integration addon is enabled.

The crash can be reproduced sometimes.
