[TxMt] help with the subversion bundle and authorized commitments

For some reason, I get the following when I try to svn commit through TextMate:

svn: Commit failed (details follow): svn: OPTIONS request failed on '/path/to/trunk/' svn: OPTIONS of '/path/to/trunk/': authorization failed ( http://svn.server.net/)

Commits work, however, through the terminal.

Regardless, I trashed the cached authorization and (for the sake of sanitation) checked out a brand new copy of the code (re-providing authorization) with the terminal, but after making a cosmetic change to a file with TextMate, a subsequent commit fails (while Terminal successfully commits the file).

Am I missing something here? I've successfully used the svn bundle with a different setup.
