If you have a grouped window list (say, many browser windows) in the task bar and you do a (normal) click on the grouped window list the window list expands and shows the individual windows. If you then do a ctrl-click on the item in the task bar (ie: the root element of the expanded window list) plasmashell crashes. Note: all "click" actions refer to a left mouse button click.
Backtrace?
I'm sorry, I'm not a C/C++ dev and have no idea how/where to find the backtrace for this.
From the crash dialog that appears - nevermind tho, I was able to reproduce the crash and got one.
OK, great that you managed to reproduce. BTW, I don't get a crash dialog when this happens.
I do :) Must be Neon screwing something up.

Git commit dc17f78ebcc76600040a8d2ef8c57b9a41a8d06e by Eike Hein. Committed on 13/02/2017 at 10:42. Pushed by hein into branch 'Plasma/5.9'. Fix crash when invoking Present Windows with the group dialog open. Summary: This fixes a regression from aeec4ae8 which unsets the taskManagerItem prop when the group dialog is shown to intentionally break window highlighting while the dialog is open. This patch instead fixes highlighting from the group dialog properly by including it in the highlight list. Also adds some extra crash guards.
