On the client I get this:

On the server I get this:

Does your repository validate? It looks like there is a bundle that is empty (or something like that) (We should handle this properly, but it looks like that is the root cause here)

[desai]

I think that this patch should make it handling things cleanly.

Root cause was a non-parseable bundle. This server side problem is fixed in [25cbe5f6b72a089e36ded5dcb4286c5c4ed228d4] (SVN r1741)
