Understood.

From your other mail it looks like you ran into the same problem, so it
definitely sounds like a problem with the repository. I don't know if you
can test this or not, but can you checkout that revision 336 and verify that
the contents of that revision are correct (i.e, there are no corrupted source
files, images, etc.). The dumpfile should show which files were modified in
that rev, as should 'svn log -r336'. I'm curious as to whether there is
actually corrupted data, or that the wrong checksum got stored somehow. It's
more than likely the former.
