I was just looking at the commits on the OpenPegasus project (http://www.ohloh.net/projects/3397/commits?sort=time_reverse&page=1) and I tried to filter by the one of the developers and it displayed an empty list. I tried several other developers and get similar results.
Is this a known problem?
Yes, this is by design. Commits can currently only be filtered by comment (which, of course, are currently blank on this project ;-). I'll put this on the to-do list...
