Relevation on edgy spits out errors when changing entries

Using edgy, revelation 0.4.7-2ubuntu2

Every time I click on a different entry, it spits out this error at me. Choosing to continue makes it go away, but changing the entry I'm viewing brings it back.

/usr/lib/python2.4/site-packages/revelation/data.py:400: GtkWarning: gtk_tree_store_get_value: assertion `VALID_ITER (iter, tree_store)' failed
