E175002: Server sent unexpected return value (500 Internal Server Error) in response to POST request for '/repos/svntest/!svn/me'

Hi

after upgrading a SVN server from 1.6 to 1.7.2 (r1207936), I am getting
this error message when committing:

svn: E175002: Commit failed (details follow):
svn: E175002: Server sent unexpected return value (500 Internal Server
Error) in response to POST request for '/repos/svntest/!svn/me'

The corresponding error on the server is:
(20014)Internal error: Can't open file '/srv/svn/repos/!svn/format': No
such file or directory

My apache configuration on the server includes:

<Location /repos/>
      DAV svn
      SVNParentPath /srv/svn/repos/
      SVNListParentPath on
...
</Location>

I am unsure what could be wrong and what those error messages mean.
Has anyone a few hints?

Thanks a lot
Pierre
