           Summary: Kmail crashes when reestablishing connection
           Product: kmail
           Version: unspecified
          Platform: Unlisted Binaries
        OS/Version: Linux
            Status: UNCONFIRMED
          Severity: crash
          Priority: NOR
         Component: general
        AssignedTo: kdepim-bugs at kde.org
        ReportedBy: sebastian at dystopianfuture.de


Application that crashed: kmail
Version of the application: 1.12.4
KDE Version: 4.3.4 (KDE 4.3.4)
Qt Version: 4.5.3
Operating System: Linux 2.6.31-1-686-bigmem i686
Distribution: Debian GNU/Linux 5.0.3 (lenny)

What I was doing when the application crashed:
After ISP-Reconnect, Kmail tries to reestablish IMAP-Connection and crashed
immediately (Pop-Dialog opens which says: Trying to reestablish....).
I press continue and it crashes.
This happenend with Kmail pre 4.3.x, was okay with 4.3.2.
Now after I upgraded my Debian Sid box to 4.3.4 from 4.3.2 this happens again.
Thank you.
