[BUG] Crash sometimes #60

Closed krisives closed 4 years ago

krisives commented 4 years ago

Describe the bug Plasma crashes. It recovers quickly, but it provides a stack trace.

To Reproduce Unclear. Happens every so often when I hover over decorations within the applet-window-buttons widget. Stack trace seems to indicate that while it's happening with that widget the actual crash is within the decoration.

Expected behavior Plasma or KDecration2 shouldn't crash.

Bug inheritance Has never happened with other decorations using the applet-window-buttons thingy.

Backtrace:

Seems to be an issue with how the unison hovering is doing it's thing. Can you check if this issue also appears in SierraBreezeEnhanced?

Closing this as I most likely won't be working on this any further (see 5f57998e).
