Application: plasmashell (5.4.0)

Qt Version: 5.4.2
Operating System: Linux 4.1.6-3-desktop x86_64
Distribution: "openSUSE 20150903 (Tumbleweed) (x86_64)"

-- Information about the crash:
- What I was doing when the application crashed:
I did set up Ibus with Chinese Character Set. I opened libreoffice 5 to find that ibus does not work in opensuse (will be reported). I looked at the character settings of libreoffice and then closed libreoffice. 
Plasma crashed. 
- Unusual behavior I noticed:

- Custom settings of the application:
Ibus with Chinese Character Set.

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