I think this can be caused by incompatible .pyc files so I would delete all the files with .pyc extension in your config folder and try again.

Ah yes. Does the SIM racktoolchange also give you the same error?

This points to the glade file 'racktoolchange.ui' but your config does not seem to use that glade panel, does it?
If it does not use it then your machine config is likely failing for another reason. Have you tried deleting the .pyc files in the python folder of your config?
