           Summary: kmail mail check freeze on imaps account if imap server
                    is restarted
           Product: kmail
           Version: unspecified
          Platform: unspecified
        OS/Version: Linux
            Status: UNCONFIRMED
          Severity: normal
          Priority: NOR
         Component: general
        AssignedTo: kdepim-bugs kde org
        ReportedBy: p92 free fr


Version:           1.9.6 (enterprise 0.20070907.709405) (using KDE 3.5.7, Kubuntu (gutsy) 4:3.5.7-1ubuntu15)
Compiler:          Target: i486-linux-gnu
OS:                Linux (i686) release 2.6.22-13-generic

I have an imap account configured with SSL encryption.

This is working fine until my imap server is stopped each night (for backup purposes) then restarted. Kmail issues the message that the imap account has been disconnected. But then I am unable to read the inbox folder again. When I try to open it kmail displays that it is receiving the content of the folder and be patient. Indicator of progress at the bottom right shows: account check : 100% and that's all.

I can change to another folder on the imap server and the content is shown. 

There is always an instance of the inbox folder checking that is hung and prevent it from beeing shown.
