           Summary: New mail check on an IMAP account (Gmail) sometimes
                    halts
           Product: kontact
           Version: 4.4.3
          Platform: Ubuntu Packages
        OS/Version: Linux
            Status: UNCONFIRMED
          Severity: crash
          Priority: NOR
         Component: general
        AssignedTo: kdepim-bugs at kde.org
        ReportedBy: kdebugs at nexustech.co.za


Version:           4.4.3 (using KDE 4.4.4) 
OS:                Linux

When Kontact runs a check on an IMAP (Gmail) account for new mnessages, the
progress indicator is stopped at some point along its progress and access to
that account is impossible (using the "abort" button does nothing), requiring a
restart of Kontact before access to that account is possible.

Admittedly this seems to occur for accounts when bandwidth is lacking (i.e. a
local mail server never has this problem) so it may be related to an IMAP
timeout issue; i.e. Kontact does not drop and retry to connect but sits
infinitely waiting for a response that never comes. This is just my best guess
however.

Reproducible: Sometimes

Steps to Reproduce:
The only possible way to reproduce this (and this is a guess as I am not
entirely sure what could cause it) would be to have an IMAP account over a very
low bandwidth/highly utilised Internet connection that could cause data to stop
and the IMAP server connection to timeout.

Actual Results:  
The check new messages status for an account stops its progress and cannot be
aborted or access to that account restored without a restart of Kontact.

Expected Results:  
If a connection goes dormant for a specific time, close connection forcefully
and attempt to reconnect again. Alternatively, ensure that the Abort button
does force an IMAP connection close.
