[pygtk] Setting user-data property

[Tobias Weber]

Hi,
every widget inherits it, but no matter what argument type I set_property('user-data', value) to I get an error. Probably cause it's supposed to be a pointer.

Now how do I attach a dictionary of custom meta data to a TreeViewColum as recommended?
