That sounds like a bug in Subversion... if the file could be committed, then we should be able to dump or otherwise deal with it, even if the name is unusual. I'd recommend you try the latest version of Subversion 1.6.x and see if the problem persists. You could also try 1.7.0 but you may want to wait on upgrading important systems to that version due to other issues you can read about on the mailing list.

The failure is in svnadmin dump, so the next svndumpfilter command isn't even getting run; it's failing before that.

You got it mostly right:

$ svnadmin help dump | head -n 1
dump: usage: svnadmin dump REPOS_PATH [-r LOWER[:UPPER] [--incremental]]

You just forgot the "-r" switch before your revision range.

svnadmin dump REPO -r 0:8233 > REPO.dump
svnadmin dump REPO -r 8234:HEAD --incremental >> REPO.dump

If you don't plan to filter the dump, you can save quite a lot of space by using deltas:

svnadmin dump REPO -r 0:8233 --deltas > REPO.dump
svnadmin dump REPO -r 8234:HEAD --deltas --incremental >> REPO.dump
