Error when converting git repo to mercurial using hg convert

Question

If I run:

hg convert /path/to/repo

I get the error:

abort: invalid mode ('r') or filename

I've checked and I think the error is a Python error, but it doesn't help me resolve the errror.

Is there any way to get more information and, ultimate fix?
