           Summary: KMail crashed when changing folder after moving a lot
                    of messages
           Product: kde
           Version: unspecified
          Platform: unspecified
        OS/Version: Linux
            Status: NEW
          Severity: crash
          Priority: NOR
         Component: general
        AssignedTo: unassigned-bugs at kde.org
        ReportedBy: kde at randomguy3.me.uk


Application: kmail (2.0.89)
KDE Platform Version: 4.5.67 (4.6 >= 20100901) (Compiled from sources)
Qt Version: 4.6.3
Operating System: Linux 2.6.35-ARCH x86_64
Distribution (Platform): Archlinux Packages

-- Information about the crash:
- What I was doing when the application crashed:

I moved a lot of messages (not sure how many, over 100 though) from a folder to
its parent, then deleted the original folder.  The message list pane looked
like it was still viewing the old folder with all the (now moved) messages in,
and an unrelated IMAP account (not a folder, the account itself) was selected
in the folder tree.  I clicked on the folder I had moved the messages to, and
KMail crashed.

-- Backtrace:
Application: KMail (kmail), signal: Segmentation fault
