gitweb - snapshot leads to 404 error

Hello!

Today I installed git and enabled it for one of my virtual hosts. I was able to create a repository and to push my local changes to it. Now if I want to create a snapshot of the repository (clicking on the snapshot link next to a repository in the project list) I only get a 404 response:

The requested URL /git/myproject.git-snapshot-HEAD.tar.bz2 was not found on this server.

There is nothing to find in the apache error logs. Any ideas why the snapshots aren't working?

Best regards

Nico
