When using the code browser only the "releases" and "trunk" top-level directories as shown. See:
However, when doing a
the repository shows more top-level directories (e.g. 'branches', 'tags', 'vendor').
Also trying to resync the repository with the code browser using the "resync" functionality in the admin section didn't help.
So it seems the code browser is somehow out of sync with the real content of the repository.
So please investigate and fix.
