Failed to start kde (qdbus assertion failed)

Hi, list

I built KDE4 from svn trunk successfully. However, I cannot
start kde.

I started X window and ran dbus first.  Then I typed

startkde > log 2>&1

There is a message in the X window screen:

Could not start D-Bus. Check your installation.

I examined the log and it told me:

startkde: Starting up...
/home/kde-devel/kde/bin/startkde: line 284: 20703 Aborted   
             
qdbus >/dev/null 2>/dev/null
/home/kde-devel/kde/bin/startkde: line 284: 20710 Aborted   
             
qdbus >/dev/null 2>/dev/null
startkde: Could not start D-Bus. Check your installation.
Warning: Missing charsets in String to FontSet conversion
kdeinit: Launched KLauncher, pid = 20720 result = 0
20720: assertion failed "(functions->mask &
~DBUS_THREAD_FUNCTIONS_ALL_MASK) 
== 0" file "dbus-threads.c" line 524 function
dbus_threads_init
kdeinit: Communication error with launcher. Exiting!
Warning: connect() failed: : Connection refused


It seemed that qdbus could not be started. So I tried to
type qdbus my self.

[kde-develfranklin ~]$ qdbus
20980: assertion failed "(functions->mask &
~DBUS_THREAD_FUNCTIONS_ALL_MASK) 
== 0" file "dbus-threads.c" line 524 function
dbus_threads_init
Aborted.

I updated the qt-copy source and re-built it, but the same
result.

Could anyone please help me with this?  Thanks a lot!


Regards,
Franklin
