Application: okular (0.21.3)
KDE Platform Version: 4.14.6
Qt Version: 4.8.6
Operating System: Linux 3.19.2-1-ARCH x86_64
Distribution: "Arch Linux"

-- Information about the crash:
- What I was doing when the application crashed:
Whenever I open MS Office documents using Okular (This involves calligra-extra plugins, providing okularGenerator_odp.so and okularGenerator_odt.so ), everything works as expected until I want to close the application. Okular crashes upon closing, producing the backtrace attached.

The crash can be reproduced every time.

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