Bug 305753

Application: kexi (2.4.0 (Calligra 2.4.0))
KDE Platform Version: 4.8.4 (4.8.4)
Qt Version: 4.8.1
Operating System: Linux 3.2.0-29-generic x86_64
Distribution: Ubuntu 12.04.1 LTS

-- Information about the crash:
- I've created a file to try kexi capabilities, with a table and a simple form (with a combobox).
- I've tried to "compact" the database (i don't know what does this feature), and then, when kexi alerted me that the database can't be compacted, i've tried to close kexi.

-- Backtrace:
Application: Kexi (kexi), signal: Segmentation fault
