Gnome System Monitor not running


I am trying to run the Gnome System Monitor on openSUSE 11.1 but it never actually appears when I click to run it from a menu e.g Computer > Status > System Monitor.

If I run it from a terminal I receive the following error:

process 5808: arguments to dbus_move_error() were incorrect, assertion “(dest) == NULL || !dbus_error_is_set ((dest))” failed in file dbus-errors.c line 278.
This is normally a bug in some application using the D-Bus library.
D-Bus not built with -rdynamic so unable to print a backtrace
*** glibc detected *** gnome-system-monitor: free(): invalid pointer: 0xbf87ac64 ***

Can anyone help?
