Well, this looks like a nested set of problems. This specific traceback has been 
fixed. (It happens when you abort a write transaction without anything written yet.)
Unfortunately that means we don't know what the real error is.

If you could update your bzr to a newer version, that would give us a better 
idea of what is happening in bzr-svn.
