ccsm doesn't start

[xcsnake@free.fr]

hello,

I have a problem with the compiz configuration & settings manager : the "ccsm"
command gives

Traceback (most recent call last):
  File "/usr/bin/ccsm", line 43, in ?
    mainWin = ccm.MainWin(context)
  File
"debian/compizconfig-settings-manager/usr/lib/python2.4/site-packages/ccm/Window.py",
line 77, in __init__
  File
"debian/compizconfig-settings-manager/usr/lib/python2.4/site-packages/ccm/Window.py",
line 361, in CatSortCompare
KeyError: 'core'

Does someone have an idea ??

Thank you

Mickaël
