Commit fails for user other than the user owning X

[Russel Winder]

From a gnome-terminal logged in as russel I did:

    sudo su - bazaarbook

in order to have a login as bazaarbook

I then went through a Bazaar branch start sequence:

|> bzr init MyNewWebsite

[Anthony Fok (foka)]

I experienced the same problem when I used bzr on remote server (no X) on Debian sid.

The same issue was brought up recently on http://irclogs.ubuntu.com/2008/09/02/%23ubuntu-devel.txt . The participants there found that the regression is caused by a change in dbus.

The workaround, as suggested in the IRC log, is to uninstall bzr-dbus for the time being.

[Stefan Lesicnik (stefanlsd)]

I also receive this.

I wanted to test the peer to peer model of bzr.

I su - to a new user and run

bzr branch sftp://stefan@localhost/home/stefan/src/zlm

and i receive
stefan@localhost's password:
