           Summary: Segfault for no apparent reason
           Product: kmail
           Version: 1.9.7
          Platform: unspecified
        OS/Version: Linux
            Status: UNCONFIRMED
          Severity: crash
          Priority: NOR
         Component: general
        AssignedTo: kdepim-bugs kde org
        ReportedBy: silver where else net nz


Version:           1.9.7 (using KDE 3.5.7, Kubuntu (feisty) 4:3.5.7-0ubuntu1~feisty2)
Compiler:          Target: i486-linux-gnu
OS:                Linux (i686) release 2.6.20-16-generic

I'm not entirely sure what I did to cause this crash. I think it happened as I clicked on an IMAP folder while kmail was trying to send an email. After kmail came back up the email was still in the outbox.

The backtrace is as follows:

Using host libthread_db library "/lib/tls/i686/cmov/libthread_db.so.1".
[Thread debugging using libthread_db enabled]
