Yes, I found the problem when running the log dialog. Since it appears to be related to log caching, I've turned that off for the moment. This helped for most of my working copies.
But I still have problems with my Tsvn WC. I thought it might just be corrupt, but then I just did the following:

- Check out new WC of Tsvn trunk, depth immediates.
The following commands on the WC root seize up:
- Commit
- Show log
- Repo-browser
The following commands work:
- Update
- Check for modifications
- Revision graph (at least it starts getting the history before I kill it)

In my original Tsvn WC, I get the attached error on Check for Modifications.
Debugging indicates that svn enters an eternal loop while trying to work upward to the WC root directory.
Nightly r20293.
