klauncher crash (due to qdbus?)

[Jaroslaw Staniek]

Hi
Reported to http://trolltech.com/bugreport-form and CC'd here.
Perhaps someone has any idea.

Platform details
Qt from KDE's qt-copy.

Compiler: MSVC 2005 SP1

Description: Crash in QDBus

What I did: KDE4's klauncher application occasionally crashes.

What I expected to see: Proper connection closing.

What I got instead:
A crash, the backtrace is as follows.
Note that QEvent::ChildRemoved event is sent to QDBusConnectionPrivate 
receiver=0x02b09400 here but we are already in its destructor 
~QDBusConnectionPrivate().
