Assertion error in get_inventory_xml

[Chris Seaton]

Hello,

I was having trouble pushing my branch earlier, but I used SFTP to  
copy it by hand and now I'm trying to branch it over HTTP but I get  
the error

bzr: ERROR: exceptions.AssertionError: <type 'NoneType'>
   at /usr/local/lib/python2.4/site-packages/bzrlib/branch.py line 952
   in get_inventory_xml

Is bzr ready for real use yet? Am being too optimistic in expecting  
to be able to get it running at the moment? I know it's only a 0.x  
release.
