You can check 'bzr config debug_flags' and add 'hpss' if it's not there
to enable more debug output related to the smart server (which bzr+ssh
uses).

Don't remove the repository, that's where the revisions you spend 2-5
hours to acquire are stored.

Instead, use 'bzr info' in the shared repository to check that it's
properly configured before 'bzr branch' and after.

I.e.:

$ bzr init-repo emacs
Shared repository with trees (format: 2a)
Location:
  shared repository: emacs
vila:~/tmp :) $ cd emacs
vila:~/tmp/emacs :) $ bzr info
Shared repository with trees (format: 2a)
Location:
  shared repository: .

Above, bzr said twice that the repository will create a working tree
("with trees").

'bzr' checks for a file named 'no-working-trees' in '.bzr/repository' to
decide whether or not working trees are created so either this file is
created in your repo or bzr is looking at a wrong place. But it *has* to
find such a file somewhere to *not* create a wt.
