Can not qclone patch queue with https

when I try to qclone my patch repository with HTTPS, I always get
{{{
#!shell
$ hg qclone https://felixschwarz@bitbucket.org/felixschwarz/trac-l10n-de\\
requesting all changes
abort: HTTP Error 404: NOT FOUND
}}}

Before I got to this state, I renamed both the repository and the patch queue (+ a couple of other operations). However I was unable to reproduce the problem with some quick experiments.

Still I can qclone the repo above only with workarounds...

Sorry for being unable to give you more details what happened.
