hg-git deploy to heroku from Lion

I have this application on my Lion machine that is in a mercurial repository so I'm using hg-git to deploy it to heroku.

~/.hgrc

[extensions]
hgext.bookmarks =
hggit =

.../project/.hg/hgrc

[paths]
default = https://validhgrepo.com

[alias]
push-heroku  = push git+ssh://git@heroku.com:appname.git

Then when I run hg push-heroku it should deploy, but instead I get:

caseys-MacBook-Air:project casey$ hg push-heroku
pushing to git+ssh://git@heroku.com:appname.git/
creating and sending data
["git-receive-pack 'appname.git/'"]

 !  Invalid path.
 !  Syntax is: git@heroku.com:<app>.git where <app> is your app's name.

abort: git remote error: The remote server unexpectedly closed the connection.

This doesn't make any sense. I feel like the error message is misleading because that repository DOES exist.

Also this works perfect on my ubuntu machine with a similar setup.

Solution

Turns out this was related to this issue. I hadn't noticed the extra slash before. I applied a patch similar to this guy and it worked for me (on latest hg, hg-git and osx).

Full details of how to install the patch:

first uninstall it
```
sudo easy_install -m 'hg-git'
```
then delete the hg-git egg file in ~/Library/Python/2.7/site-packages
install as directory
```
 sudo easy_install -Z 'hg-git'
```
open ~/Library/Python/2.7/site-packages/hg_git..../hggit/git_handler.py

apply patch by hand (mine was more like line 1118)
