"No changesets yet" if git has no "master" branch
We have a read-only Mirror of qtbase  on our kallithea. But kallithea does not show any changeset in web overview. The repository is complete and we can clone/pull from it. Also a separate "cgit" can show the content of the repository.
The problem seems to be that qtbase does not have a "master" branch (they call it "dev"). If I create a fork of that repository and push a "master" branch it will be shown in web overview of kallithea.
