NullPointerException: java.lang.NullPointerException

error caused by lines 340-346 in resources.py

         if src:
             source_vars = dict(
                 v for v in [(k, getattr(self,k,None)) for k in
self.source_vars]
                 )
             source_vars.update(
                 v for v in d.iteritems() if v[0] in self.source_vars
                 )

From the trace is:

self._raw_regexp = r"|".join("(%s)" % k (for k in dct.keys()))

correct?

Shouldn't the generator expression be

(k for k in dct.keys()))

Not that this should result in an NPE -- but I just want to understand.

Aside from what looks like a syntax error in the example code, I'm
almost positive that this was related to nested generator expressions,
which do not produce an NPE any longer.  Closing.
