Description Piotr Mierzwinski 2016-01-16 13:17:45 UTC

I have at right screen edge the entire panel/bar (default placed on bottom). Bar is a bit wider to fit two columns of icons placed in System tray. I have 8 icons placed in System tray (no one app.  has deprecated notification system).
Plasmashell crashed when I hide one icon (I tested one placed in right bottom corner of System Tray) and try to get context menu clicking on icon from second row (counting from bottom) and later from third row. Here I clicked on "BlueTooth" icon and crash happens. Sometime is happens when I click in icon from second row and sometime after clicking on third row).

I reproduced it on Mageia 6 (second row in System task) and in KaOS. All of them were up-to-date on day 16/01/2016.

Unfortunately stack trace is useless, like said "Crash Reporting Assistant" I  have already installed debug packages related to plasmashell.

Comment 1 Marco Martin 2016-03-09 12:05:36 UTC

Systemtray implementation is changed, this should be one of the problems fixed.
