[Zope-CMF] DCWorkflow problems with the Hotfix_2001_07_25

[Renato Ramonda]

Hi everibody,
has anyone tried the Hotfix_2001_07_25 on a Zope+CMF+DCWorkflow?

On my machines (Zope 2.3.2 and 2.3.3 + CMF 1.1 + DCWorkflow 0.2)
when I try to access the "Transitions", "Variables" or "Worklist" 
tab I get the following error:

Error Type: AttributeError
Error Value: 'None' object has no attribute 'replace'

Traceback (innermost last):

Any insights on what could cause this?
I removed the Hotfix product and all started working again...
