Bzrlib does not understand https+webdav even though webdav plugin is installed (works from command line)

Hi,

I'm trying to pull from a branch's parent using bzrlib API. The parent
location is using https+webdav. When I run this code I get an exception
wiht the message:

Unsupported protocol for url "https+webdav://.....

If I branch from the command line using the exact same address there is
no problem. bzr plugins shows that the webdav plugin is installed.

My python code looks like this:

try:
                    parent_location = branch.get_parent()
            	
                    if not parent_location is None:
                        parent_branch = Branch.open(parent_location)
                        branch.pull(parent_branch)
                except BzrError, e:
                    print >>sys.stderr, \
                            'Could not pull from parent for branch %s:
%s' % (branch_emailer.path, e)


What am I doing wrong?

Cheers,

Nick
