Application: plasmashell (5.10.5)

Qt Version: 5.9.1
Frameworks Version: 5.37.0
Operating System: Linux 4.12.9-1-pae i686
Distribution: "openSUSE Tumbleweed"

-- Information about the crash:
- What I was doing when the application crashed:

I was installing a small number of updates via the "Software Updates" widget. The crash - which happens regularly, though not every time - seems to occur at the end of the installation process. The updates appear to get correctly installed, and Plasma recovers nicely enough after the crash - but I get a "crash icon" in the system tray that will open the Crash Reporting Assistant ... so this time I decided to use it to report the bug (if that is what it is). Brgds.

The crash can be reproduced sometimes.

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