           Summary: kmail composer hangs whole kontact when writing mails
           Product: kontact
           Version: unspecified
          Platform: Gentoo Packages
        OS/Version: Linux
            Status: UNCONFIRMED
          Severity: normal
          Priority: NOR
         Component: mail
        AssignedTo: kdepim-bugs at kde.org
        ReportedBy: meyerm at fs.tum.de


Version:           unspecified (using KDE 4.5.4) 
OS:                Linux

I just updated to kdepim 4.4.9 using KDE 4.5.4 and now when composing an email
kontact hangs after a while. No more interaction is possible even though the
cursors keeps blinking and the window repaints itself when it was hidden (using
no desktop effects). However, killing kontact seems to be the only possibility
to get a working client back. So it's a data loss of the mails opened in the
composer.

Reproducible: Sometimes

Steps to Reproduce:
Answer to a mail, write half a paper and then watch it hang forever... (it
happened for the first time in the moment of sending a mail).

Actual Results:  
hang

Expected Results:  
continue editing/send

I started kontact from konsole:
http://kde.pastey.net/144697

After killing with -9, it said:
meyerm at yavin ~ $ *** KMail got signal 15 (Exiting)

(process:20899): GLib-WARNING **: g_main_context_prepare(): main loop already
active in another thread
kontact: Fatal IO error: client killed
QCoreApplication::postEvent: Unexpected null receiver
