More information. The problem seems to be in _set_name() of class Widget of 'turbogears/widgets/base.py'.
If I remove the following lines (87-88) of that file then my project
will work:
if (hasattr(self,'label') and hasattr(self.label,'name')):
self.label.name = value
If I leave them in I get a the bus error caused by I think infinite
recursion. I dont know enought about the code to debug further but that
might give people somewhere to start.
