Bug 326552

Application: calligrawords (2.7.2)
KDE Platform Version: 4.11.2
Qt Version: 4.8.4
Operating System: Linux 3.11.0-12-generic i686
Distribution: Ubuntu 13.10

-- Information about the crash:
- What I was doing when the application crashed:
I'm trying to create a three-folded brochure. When clicking into one frame and then trying to select a paragraph style, the program crashes (it actually crashes all the time in different situations, but I'll post bug reports separately).

The crash can be reproduced sometimes.

-- Backtrace:
Application: Calligra Words (calligrawords), signal: Segmentation fault
