Application: kexi (2.8.3)
KDE Platform Version: 4.13.2
Qt Version: 4.8.6
Operating System: Linux 3.13.0-29-generic x86_64
Distribution: Ubuntu 14.04 LTS

-- Information about the crash:
- What I was doing when the application crashed:

* A query was open in a tab
* I edited the design of a table used by the query (changed the name of a field)
* Kexi warned that it must closes the object using the query first
* I click OK, close it
* Kexi crashed on me

The crash can be reproduced every time.

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