I created a new repo, and cloned it successfully via ssh.
Then I browsed to the repo's wiki and tried to follow the instructions for cloning the wiki. This fails as follows:
jean@klippie:~/repos/git$ git clone git@bitbucket.org:user/project.git/wiki project-wiki
Initialized empty Git repository in /home/jean/repos/git/project-wiki/.git/
conq: repository access denied.
fatal: The remote end hung up unexpectedly
Any idea what's going wrong?
