I've a problem with my svn repo. I cannot use it, I even cannot dump it.

svnadmin verify repo

returns

Can't set position pointer in file 'svn/db/revs/0/0'

When I try to dump repo (no matter what revision range), console output shows:

* Dumped revision 0.
svnadmin: Final line in revision file missing space

I've googled that this may be connected with wrong version apr apache2 library, but I have other repositories which work good, so I thing this isn't the case.

Is there any way to save at least some files from my repo? Can svn repo get corrupted so easily (probably after power-cut, however I'm not sure).
