           Summary: KMail Crashes When queuing multiple operations
           Product: kmail
           Version: 1.13.3
          Platform: Slackware Packages
        OS/Version: Linux
            Status: UNCONFIRMED
          Severity: crash
          Priority: NOR
         Component: general
        AssignedTo: kdepim-bugs at kde.org
        ReportedBy: arcfide at sacrideo.us


Application: kmail (1.13.3)

Qt Version: 4.6.2
Operating System: Linux 2.6.33.4 x86_64
Distribution (Platform): Slackware Packages

-- Information about the crash:
I'm not sure what operation is causing the problem here, but when I delete more
than one message or I am queuing up multiple operations, especially when
combining operations which write and read from the folder (E.G. -- Moveing a
few messages, and while those operations are copmleting, delete another
message, and further still select a new message to read or move), I'll get this
sort of crash. I can replicate it pretty reliably, but I haven't figured out
exactly what causes it aside from just queuing up a lot of operations in
semi-rapid succession.

The crash can be reproduced every time.
