After compiling kdelibs with the new qt-dbus under /trunk/kdesupport,
kbuildsycoca crashes.  This occured immediately after shifting between
the dbus bindings in dbus and the "native" bindings in kde.  Below is
the method that was used to compile the libs:
$KDEDIR=/home/kde4/kde
$QTDIR=/home/kde4/qt-unstable

Dbus:
>cd dbus
>make -f Makefile.cvs >./configure --prefix=$KDEDIR
--libdir=$KDEDIR/lib --bindir=$KDEDIR/bin --includedir=$KDEDIR/include
--localstatedir=/var
>make
>make install

qt-copy:
>svn co svn://anonsvn.kde.org/home/kde/trunk/qt-copy
>cd qt-copy && ./configure -qt-gif -no-exceptions -debug -fast
--prefix=$HOME/qt-unstable && make && make install

qt-dbus:
>svn co svn://anonsvn.kde.org/home/kde/trunk/kdesupport/qt-dbus
>mkdir qt-dbus-build
>cd qt-dbus-build
>PKG_CONFIG_PATH=/home/kde4/kde/lib/pkgconfig/ cmakekde ../qt-dbus

kdelibs4_snapshot:
>svn co svn://anonsvn.kde.org/home/kde/branches/work/kdelibs4_snapshot
>mkdir kdelibs4_snapshot-build
>cd kdelibs4_snapshot-build
>PKG_CONFIG_PATH=$KDEDIR/lib/pkgconfig/:$QTDIR/lib cmakekde ../kdelibs4_snapshot


I've included this because I'm not sure if the method I chosen to
compile the libs is at fault.  Additionally, here are backtraces and
debug messages.
backtrace:

Debug:
Session management error: Could not open network socket
kbuildsycoca: FATAL: Session bus not found
KCrash: crashing... crashRecursionCounter = 2
KCrash: Application Name = kbuildsycoca path = <unknown> pid = 22451
Warning: connect() failed: : Connection refused
KCrash cannot reach kdeinit, launching directly.
kdeinit: Pipe closed unexpectedly: No such file or directory
kdeinit: Pipe closed unexpectedly: No such file or directory
kdeinit: Communication error with launcher. Exiting!

It appears that it's a result of the session bus not being found which
may be caused by the change to qt-dbus.  Any ideas?
