node_comment breaks sort by node author in Views

I was setting up a view to be sorted by node author, but found that the query being generated
was using the node_comment table as the source for the user name and joining that through the nid.
Since not all nodes have a comment this was losing the user name on most nodes.

It should be joining to the users table through node.uid value to get the name.

Not sure if this is a Views issue or an issue with this module.
