           Summary: "version conflict"-dialogue blocks kontact and does
                    not accept mouse-clicks
           Product: kmail2
           Version: 2.1.0
          Platform: openSUSE RPMs
        OS/Version: Linux
            Status: UNCONFIRMED
          Severity: major
          Priority: NOR
         Component: general
        AssignedTo: kdepim-bugs at kde.org
        ReportedBy: sven.burmeister at gmx.net


Version:           2.1.0 (using KDE 4.6.4) 
OS:                Linux

Sometimes the "version conflict"-dialogue does not accept clicks, i.e. there is
no way to get rid of it but kill kontact.

I attached gdb to kontact and it gave me the following backtrace:

HAving to kill kontact can lead to data loss.

Reproducible: Sometimes

Steps to Reproduce:
Wait until you get the "version conflict" dialogue. There are plenty of bugs
filed on what triggers them, e.g. changing an email's status while it is
fetched from the server.

Actual Results:  
blocking GUI? (@bugzilla admins: Most the times forcing the reporter to fill in
these fiels is useless!)

Expected Results:  
Guess! Non-blocking GUI. No offense to the kmail developers, not their fault
that these fields are required now, though being pretty useless most of the
time)
