           Summary: Kopete freezes when it is started at same time as
                    KMail
           Product: kopete
           Version: SVN
          Platform: Gentoo Packages
        OS/Version: Linux
            Status: UNCONFIRMED
          Severity: normal
          Priority: NOR
         Component: general
        AssignedTo: kopete-bugs at kde.org
        ReportedBy: frederic.coiffier at free.fr


Version:           SVN
OS:                Linux

It seems there is a race condition when Kopete and KMail (or maybe
akonadiserver) are started at the same moment. It occurs when the KDE session
is restored after login.
In this case, Kopete icons in systray doesn't appear : only the process appears
in ps. At the same times, KMail is unable to refresh some folders.

Reproducible: Sometimes

Steps to Reproduce:
1. Configure KDE to restore last session with KMail and Kopete
2. Logout/login
3. When Kopete and KMail are launched, sometimes Kopete freezes

It occurs one out of 5-10 times.

If kopete process is killed, KMail is able to refresh its folders.

Actual Results:  
The Kopete process remains blocked with this backtrace :
