Application: plasmashell (5.3.2)

Qt Version: 5.4.2
Operating System: Linux 4.1.2-gentoo x86_64
Distribution: "Gentoo Base System release 2.2"

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

I was away from the computer. In the meantime, it was automatically locked. When I came back and unlocked it, I found Plasma had crashed.

I would have marked this as a duplicate of the several other reports, but the "Suggest this crash is related" button of DrKonqi is broken: It has no effect whatsoever.

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