Description

Hi developers,

I have found a bug which causes QGIS to crash.
It can be reproduced when you try to edit a layer which is in a different mapset than your current one and where you do not have write-privileges.

A Warning-window pops up and tells you that you are not the owner of the layer, where you can only print 'OK'. After hitting OK, QGIS segfaults.

Here is a gdb-bt:
...

Perhaps this is of some help.
Thank you for looking into this.
