Initialising a repository with a README fails

Creating a repository from the web interface (0.12.0rc3) with the "create initial README.md" option checked does not work: The interface afterwards fails to load the README and the logs have errors:

Completed 500 Internal Server Error in 156ms (ActiveRecord: 40.3ms)

Errno::ENOENT (No such file or directory @ rb_sysopen - /var/opt/gitlab/git-data/repositories/tuomov/secondtest.hg/.hg/git-mapfile):

lib/gitlab/git/repository.rb:377:in `initialize'
lib/gitlab/git/repository.rb:377:in `open'
lib/gitlab/git/repository.rb:377:in `hg_sha_map'
lib/gitlab/git/repository.rb:401:in `hgsha_from_sha'

Moreover, the README.md is not to be found when pulling the Mercurial repository.

Probably this is due to the one-way hg-git bridge, and it might be simplest to disable the README-creation option for now?
