New crash information added by DrKonqi

DrKonqi auto-attaching complete backtrace.

Note: the crash happens on click, however the "standard" notification (with the detail / pause / cancel) works fine.

Closing it and clicking on the faulty taskbar icon does crash plasmashell but also reopen the Dolphin notification as expected.

Unsure what to understand form this behavior

I think I have the same crash:
