           Summary: KMail crashed after clicking on a message
           Product: kmail
           Version: 1.9.50
          Platform: unspecified
        OS/Version: Linux
            Status: UNCONFIRMED
          Severity: crash
          Priority: NOR
         Component: general
        AssignedTo: kdepim-bugs kde org
        ReportedBy: Regnaron web de


Version:           1.9.50 (using 4.00.80 (KDE 4.0.80 >= 20080104), Gentoo)
Compiler:          i686-pc-linux-gnu-gcc
OS:                Linux (i686) release 2.6.22-gentoo-r9

I just tried to move a message via drag and drop from an IMAP folder to a local folder. After having successfully copied(!) the first (already read) message, KMail crashed as soon as I clicked on the second (unread) message (in order to drag and drop it)
Remark: This crash just also occurred after clicking on a (read) mail directly after starting Kontact.

The backtrace for this (regrettably not reproducible) crash was:

Using host libthread_db library "/lib/libthread_db.so.1".
[Thread debugging using libthread_db enabled]
