Looks as if your catalog were very old and still has entries
with request relative resolution.

Replace "assert(obj)" with

	if not obj:
	   # here the assert would fail
	   # determine its path for later analysis
	   path = brain.getPath()
	   # ensure, you can see "path" somehow
	else:
	   # here the assert would pass
	   ...

With this information, you can try to analyse the problem
in an interactive Python interpreter.
