KnitPack not compatible with Knit?

[Stefan Monnier]

   bzr clone http://people.samba.org/bzr/jelmer/bzr-rebase/trunk rebase

fails with

   bzr: ERROR: Repository KnitPackRepository('file:///home/monnier/src/bzr/.bzr/repository/') is not compatible with repository KnitRepository('http://people.samba.org/bzr/jelmer/bzr-rebase/.bzr/repository/')

So I cloned it into its own repository, and then tried to upgrade it:

   % bzr upgrade rebase 
   starting upgrade of file:///home/monnier/tmp/rebase/
   making backup of tree history
   file:///home/monnier/tmp/rebase/.bzr has been backed up to file:///home/monnier/tmp/rebase/backup.bzr
   if conversion fails, you can move this directory back to .bzr
   if it succeeds, you can remove this directory if you wish
   starting repository conversion
   bzr: ERROR: Cannot convert to format <RepositoryFormatKnitPack1>.  Does not support rich root data.
   % 

Is that expected?
