Bug 290660

Application: kmail (4.7.3)
KDE Platform Version: 4.7.3 (4.7.3)
Qt Version: 4.7.4
Operating System: Linux 3.0.0-15-generic x86_64
Distribution: Ubuntu 11.10

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

I created a folder, selected others brothers folders to put in this one created but the parent folder was selected too, then i decided to deselect it (because the moving didn't want to proceed) and it was so logical! When i was  deselecting this parent folder the crash happened!

-- Backtrace:
Application: KMail (kmail), signal: Segmentation fault
