Upgrading to 1.6 from 1.3 issues.

[Raindog]

Hi,

Today when I tried to upgrade my bzr install to 1.6 I had this issue 
when attempting to commit to the branch:

bzr: ERROR: Unable to connect to target of bound branch 
BzrBranch6('file:///C:/xxxxxxxxx') => bzr+ssh://xxxxxxxxx/: Not a 
branch: "bzr+ssh://xxxxxxxxx/".

but when i revert the server back to 1.3, the issue goes away. What is 
the best way to resolve this?

Thanks
