Need help for xfce4-menueditor

[Liu Mingming]

hi,

Packages:
        libxfce4util-4.4.1
        libxfcegui4-4.4.1
        libxfce4mcs-4.4.1
        xfce-mcs-manager-4.4.1
        xfce4-panel-4.4.1
        xfce-utils-4.4.1
        xfdesktop-4.4.1

After installing XFCE with packages are listed , window manager via 
Metacity.

When I run xfce4-menueditor from the command line, it segfaults and 
causing xfdesktop crashes.

Here is the result from gdb.
 
        #0  0x408ba524 in g_atomic_int_get () from /usr/lib/libglib-2.0.so.0
        #1  0x4087439c in g_object_unref () from 
/usr/lib/libgobject-2.0.so.0
        #2  0x00012c20 in menueditor_main_window_init ()
        #3  0x40885cdc in g_type_create_instance () from 
/usr/lib/libgobject-2.0.so.0
        #4  0x40876f00 in ?? () from /usr/lib/libgobject-2.0.so.0

Thanks, waiting for the hints.
