Bug 277682

Application: kexi (2.3.3 (KOffice 2.3.3))
KDE Platform Version: 4.6.2 (4.6.2)
Qt Version: 4.7.2
Operating System: Linux 2.6.38-10-generic i686
Distribution: Ubuntu 11.04

-- Information about the crash:
- What I was doing when the application crashed:
From a very basic database with 2 tables and a query, I tried to modify the query (in the design mode). I add a new row in the "Query Columns" and want to save it.
When I click on the save button it always crash.

The crash can be reproduced every time.

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