yumi Error message

[Peter Cannon <peter@xxxxxxxxxxxxxxxxxxxxx>]

Hi All

Did an update this morning and yumi was upgraded however when I do $ yumi I 
get this error message any ideas?

Traceback (most recent call last):
  File "/usr/share/yum/yumgui.py", line 9, in ?
    import clientStuff
ImportError: No module named clientStuff
