Hi Conor,
I will have a detail look a at your patch in the next days. I am at the
moment not real sure if I can add the new method to the 1.2 branch.

Can you tell me something about the underlying problem?

If you want to access a file a an earlier revision, which has been

No idea. Do you have the same problem if you use the command line client?
