Comment 6 for bug 230341

I had both of the same problems (the ValueError, and not handling prop changes to svn root dir) a while ago. I fixed the first problem. For the second one, I was a bit worried about breaking things for others, so I added a descriptive error message, prompting the user to slightly modify their dump file:

Your dump file has a node that's trying to change something about the empty root path '' in your svn repo. Try adding the following just before the line that says 'Revision-number: 1' near the start of your dump file (make sure your text editor doesn't strip trailing whitespaces from lines or otherwise change line endings when saving to the dump file):

Node-path:
Node-kind: dir
Node-action: add
Prop-content-length: 10
Content-length: 10

PROPS-END

Does the latest trunk (rev21) solve the problem?
