            Status: UNCONFIRMED

        AssignedTo: kdepim-bugs kde org
        ReportedBy: krop free fr

KDEPim Rev. : 775116

This bug is reproducible. Two IMAP accounts :
- Account #1 with a subfolder in INBOX
- Account #2 with no subfolder.

Dragging a subfolder from #1/INBOX to #2/INBOX crashes kmail.

(poor,sorry) backtrace : 

Application: KMail (kmail), signal SIGABRT
