Bug 366325

Application: ksmserver ()

Qt Version: 5.5.1
Operating System: Linux 4.1.27-27-default x86_64
Distribution: "openSUSE Leap 42.1 (x86_64)"

-- Information about the crash:
System updated and on  a re-boot Plasma crashed for the OpenSuSE LEAP 42.1 distribution.  Dumbing down kernel to see if it works.  This has been the typical workaround until someone relaizes the mistake in packaging.

The crash can be reproduced every time.

-- Backtrace:
Application: ksmserver (ksmserver), signal: Aborted
Using host libthread_db library "/lib64/libthread_db.so.1".
