Bug 368223

Application: plasmashell (5.5.5)

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:
- What I was doing when the application crashed:
After seeing cursor hesitate to start and pause for a second or two irratically, rebooted (to clear any memory leak).   Closed KDE wallet window (not used).  Closed p/w window for Wi-Fi (not used at this time, on wired LAN).  Then crash.

- Unusual behavior I noticed:
Hesitation in the cursor movement, which is really annoying.  Makes it hard to select.

-- Backtrace:
Application: Plasma (plasmashell), signal: Segmentation fault
Using host libthread_db library "/lib64/libthread_db.so.1".
