Description Christophe Marin 2008-02-15 13:33:01 UTC

Version:           1.9.50 (using 4.00.62 (KDE 4.0.62 >= 20080213), compiled sources)
Compiler:          gcc
OS:                Linux (i686) release 2.6.24-7-generic

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 :
