Problems pushing to launchpad from bzr on Debian

Hi,

If I try to create a branche which does not exist, I get the folowing error:

peter:/# bzr push sftp://bazaar.launchpad.net/~sipman-devel/sipman.net/test2
bzr: ERROR: [Errno 2] No such file: u'/srv/bazaar.launchpad.net/push-branches/00/00/88/ed/.bzr/repository/inventory.kndx': [Errno 2] No such file or directory: u'/srv/bazaar.launchpad.net/push-branches/00/00/88/ed/.bzr/repository/inventory.kndx'

If I try to push an existing branch I get the error

peter:/# bzr push sftp://bazaar.launchpad.net/~sipman-devel/sipman.net/test1
bzr: ERROR: File exists: u'/~sipman-devel/sipman.net/test1': mkdir failed: unable to mkdir

Trying the stuff with the below command seems to do someting, but results for the seccond time in creating an message like
peter:/# bzr push lp:~sipman-devel/sipman.net/testing
0 revision(s) pushed.
peter:/# bzr push lp:~sipman-devel/sipman.net/testing
bzr: ERROR: Error(s) parsing config file /root/.bazaar/locations.conf:
Invalid line at line "0".
peter:/#
peter:/# cat /root/.bazaar/locations.conf
[""]
push_location = file:///lp%3A%7Esipman-devel/sipman.net/testing/
peter:/#
I guess it is not actually uploading the stuff.

I am using
peter:/# bzr --version
Bazaar (bzr) 0.11.0
  from bzr checkout /
    revision: 2

bzr: ERROR: Error(s) parsing config file /root/.bazaar/locations.conf:

How can I start using launchpad with bazaar??
