rc3 gitweb is broken, won't deliver snapshots

gitweb in 1.5.3-rc3 fails to deliver snapshots in any useable format
(bzip2, gz, or zip). Clicking on a link seems to work, but the
delivered file as stored on my system is empty. No error messages
appear anywhere I can find. I am hosting gitweb on FC7 using lighttpd,
if that matters.

The snapshot service at git.kernel.org also seems broken, I don't know
what gitweb is running there so don't know if the issue is related.

I have fixed this for my use by reverting the following commits

3473e7df5f8c7f8dc3e2c3f2fdc99a1d1a719c16 gitweb: More detailed error
messages for snapshot format
a781785d8f1eb7adf05a24b121104716a086a67a gitweb: Fix support for
legacy gitweb config for snapshots
a3c8ab30a54c30a6a434760bedf04548425416ef gitweb: snapshot cleanups &
support for offering multiple formats

The snapshot problem first appears when a3c8ab30a54 is applied.
