Application: kwalletmanager (1.9)
KDE Platform Version: 4.8.4 (4.8.4)
Qt Version: 4.8.2
Operating System: Linux 3.2.0-3-amd64 x86_64
Distribution: Debian GNU/Linux testing (wheezy)

-- Information about the crash:
To reproduce:
* Open a wallet for view/edit
* Create your own or use existing folder, but "Maps" has to have no entries
* Create a Name to Value map (any name), and select it for editing
* Right click on view/edit half, and create new entry
* Click "X" field to remove just created map entry (and N2V Map key is empty)
* Position your mouse on folder list and select whatever
* When editor loses focus, it's going to ask you if you want to save the changes
* To crash app - select "Yes"

The crash can be reproduced some of the time.
