Hello,

I just wanted to rename a local mail folder (maildir) that had one subfolder. So that I opened the properties of it (the parent folder), changed the name and hit ok. Then there appeared error message saying something about error when opening the subfolder and that it is missing. The non-ascii character of the new parent folder name was messed (there should have been "Latin Small Letter A with acute" in it but it appeared as two characters unknown to me) while the subfolder name was ok. When I clicked OK, kmail crashed immediately.

I can reproduce the bug.

The backtrace follows:

 [?1034hUsing host libthread_db library "/lib/libthread_db.so.1".
