Application: plasma-desktop (4.11.14)
KDE Platform Version: 4.14.3
Qt Version: 4.8.6
Operating System: Linux 3.16.7-7-desktop x86_64
Distribution: "openSUSE 13.2 (Harlequin) (x86_64)"

-- Information about the crash:
Plasma Desktop Crashes when trying to add 'world clock' widget (plasmoid).

EveryThing CRASHes on 4.14.3 x86_64... Usually while closing it or by shutdown.

This will be my last bug report. You've marked every one 'invalid' when they are NOT as it's YOUR shit that is crashing and generating the report. 
There is NOTHING 'good' about 4.14.3... It like everything these days has become 'Gaycentric' Crap. And I'm the bad guy for being fed up with the inept coders, more concerned with 'fuzy' look than functionality.... SAD!

The crash can be reproduced sometimes.

-- Backtrace:
Application: Plasma Desktop Shell (plasma-desktop), signal: Segmentation fault
