[Python-apps-team] Bug#785581: mercurial-git: Cloning fails with "NotImplementedError"

[Nikolaus Rath]

Package: mercurial-git
Version: 0.6.1-2
Severity: normal

Using the jessie package, I don't seem to be able to interact with git 
repositories. Example:

$ hg clone git+http://git.gnus.org/cgit/gnus.git/
destination directory: gnus.git
** Unknown exception encountered with possibly-broken third-party extension git
** which supports versions 3.0.1 of Mercurial.
** Please disable git and try your action again.
** If that fixes the bug please report it to https://bitbucket.org/durin42/hg-git/issues
** Python 2.7.9 (default, Mar  1 2015, 12:57:24) [GCC 4.9.2]
** Mercurial Distributed SCM (version 3.1.2)
** Extensions loaded: rebase, color, git, purge, strip, mq, histedit
