I'm seeing the same issue (with the CouchDB project which has some obsolete/incorrect enlistments). Tried with Safari 3.1 and Firefox 3.0b4, both on Leopard. Clicked "Delete", get Javascript ... [More] confirmation dialog, clicked "Okay", get XML response with okay. The enlistments don't actually seem to get deleted, though. [Less]

The CouchDB project has failed to get updated for almost two months now. What's up with that?

Is there any news on this?

Agreed, not counting docstrings in Python projects results in flawed metrics. Pretty much all Python projects have the "Few source code comments" annotation, even if they are extremely well commented via docstrings.
