--- Comment #3 from Sven Eden <sven.eden at gmx.de> ---
Unfortunately I have to add my backtrace by hand. DrKonqi lets me log in and
find this report, but when I want to attach my report and click on "continue",
nothing happens. :-(
The crashing Thread 1 looks similar, but not exactly equal.
However, Plasma crashed after I issued
"akonadictl stop"
in a console. I think that this is odd.
I am using:
System : Gentoo x86_64
Framework: 5.29.0
Plasma : 5.8.4
Apps : 16.12.0
QT : 5.7.1
GCC : 5.4.0
GLIBC : 2.23
Could this be some sort of race condition?
-- Backtrace:
Application: Plasma (plasmashell), signal: Segmentation fault
