unable to commit in linked subdirectory of repository checkout

system: linux
subversion: v1.7.x

this problem starts when using version 1.7 of subversion.
until 1.6 every sub-dir had its own '.svn', so wherever i was, all information to commit update was available.
now there's only one, where one checked out the repo.
this is problematic when having somewhere else a symbolc-link to a sub-dir of that checkout.
it's impossible to do anything with svn on that link because svn can't find the repository data and always returns:

svn: E155007: ' .... filename ..... ' is not a working copy

because of many automated process / web-server-scripts / etc. that access the data in our case, it would be very
beneficient if such things would still be possible with svn 1.7... otherwise we'd be stuck with last release of v1.6,
because it would mean to rewrite a very large amount of scripts to adapt to such changes...

suggestion: have a symbolic link (on supported systems, like linux, unix, etc.) that points to the .svn-dir where the
base-path of the checkout can be determined and therefore the repositry-url, etc.
