           Summary: kmail crashes if imap (not dimap) check triggered when
                    files and folders are deleted
           Product: kmail
           Version: 1.13.5
          Platform: Debian testing
        OS/Version: Linux
            Status: UNCONFIRMED
          Severity: crash
          Priority: NOR
         Component: general
        AssignedTo: kdepim-bugs at kde.org
        ReportedBy: envite at rolamasao.org


Application: kmail (1.13.5)
KDE Platform Version: 4.4.5 (KDE 4.4.5)
Qt Version: 4.6.3
Operating System: Linux 2.6.32-5-amd64 x86_64
Distribution: Debian GNU/Linux testing (squeeze)

-- Information about the crash:
a) Kmail does not refresh correctIy: I had kmail showing no subfolders nor
messages on certain folder on one IMAP account. I was sure they were there
since I have direct access to the server and the files and directories were
there when I did 'ls'. Moreover, if I tried to create a subfolder with the
appropiate name, Kmail rejected the creation with a "This folder already
exists" message, yet continued showing an empty folder. F5 didn't shown the
content.
b) I deleted the whole content of $HOME/.kde/share/apps/kmail/imap to force
kmail to refresh from the server instead of using uncorrect stale info. Then,
kmail started to show strange errors relative to the deleted folders in
$HOME/.kde/share/apps/kmail/imap and crashed.

Section a) of the bug has the ability to cause data loss: What if I decide to
delete the folder on the IMAP server trusting kmail assertion that it is empty
even when I hit F5?

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