Application: calligrawords (2.4.0)
KDE Platform Version: 4.8.5 (4.8.5)
Qt Version: 4.8.1
Operating System: Linux 3.2.0-36-generic x86_64
Distribution: Ubuntu 12.04.1 LTS

-- Information about the crash:
- What I was doing when the application crashed: I was working in a document which contained a table with too many rows, which ran on to an extra page. When trying to back space to remove the empty page at the end of the document, all text disappeared leaving a single blank page. The information and table had been pasted in from a Libre Office document which I was trying to modify. I had been having crashes with Libreoffice when trying to save documents, so tried Calligra to modify the document.

The crash can be reproduced some of the time.

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