           Summary: kmail crashes when deleting mails from online IMAP
                    account
           Product: kmail
           Version: unspecified
          Platform: Compiled Sources
        OS/Version: Linux
            Status: UNCONFIRMED
          Severity: crash
          Priority: NOR
         Component: general
        AssignedTo: kdepim-bugs at kde.org
        ReportedBy: marc at links2linux.de


Version:           4.2.91 (using Devel)
OS:                Linux
Installed from:    Compiled sources

This crash seems to be timing related, but I can reproduce it like that:

* have an IMAP account with some mails (at least 100 or so)
* place focus in the list view (above mail view part)
* have the simple list view (old threading style by date, no grouping by month
or something)
* now mark many mails by using "shift-cursordown", hold down the button for >3
seconds so the cursor "runs"
* then hit "del"-button quickly before kmail can update the mail view with the
current mail
-> kaboom!
