Catalog doesn't take the Vocabulary object itself as an argument. It
takes the (string) id of an acquirable Vocabulary. If you don't specify
a string, it creates a standard non-globbing lexicon (Although a
ZCatalog creates a globbing lexicon, go figure). Something like this
should work (Assuming your product is an acquisition wrapper e.g. by
subclassing Acquisition.Implicit):

my_vocab = Vocabulary(globbing=1)
my_cat = Catalog(vocabulary='my_vocab')

I'm completely unsure why it was implemented this way. I can kinda
understand for ZCatalog, but not really for Catalog. Anyone care to
explain??

or you could do this without using acquistion, but you wind up creating
the vocabulary twice:

my_cat = Catalog()
my_cat.lexicon = Vocabulary(globbing=1)
