Your initial push doesn't say anything about failing, just taking a while.

Your symptoms match the case when a bzr meta-directory exists, but the
branch directory does not. (a .bzr/ dir exists, but .bzr/branch/ is
missing.) That can happen if someone starts pushing to a branch and
interrupts it. The *next* push would show the symptoms you describe. (it
would fail to notice that the branch should be stacked, so create a
complete new copy of the history in the target location.)

Title:
  branch not stacked if first push is interrupted

Status in Bazaar Version Control System:
  Confirmed
Status in “bzr” package in Ubuntu:
  New

Bug description:
  I did the following:
  $ lp:~ubuntu-on-ec2/ubuntu-on-ec2/live-build live-build.dist
  $ bzr branch live-build.dist -r 1811 cloud-images
  $ cd cloud-images
  $ # manually apply revision 1813, 1814 , the point of this was to ditch my accidental merge in 1812.

  Then
  $ bzr push lp:~ubuntu-on-ec2/live-build/cloud-images
  This transport does not update the working tree of: bzr+ssh://bazaar.launchpad.net/~ubuntu-on-ec2/live-build/cloud-images/. See 'bzr help working-trees' for more information.
  Created new branch.

  The above too a while (minutes). I wondered why the message , which I
  suppose is due to repository formats or something, and then tried
  again:

  $ bzr push lp:~ubuntu-on-ec2/live-build/cloud-images
  #### 20 minutes or more later:
  254912kB   244kB/s | Fetching revisions:Inserting stream
  259070kB   237kB/s | Fetching revisions:Inserting stream

  Eventually that reported:
  No new revisions to push.

  If I do the following on oneiric, i'll see something like:
   $ bzr branch lp:~ubuntu-on-ec2/live-build/cloud-images
   273670kB  1957kB/s \ Fetching revisions:Inserting stream:Estimate 104073/106426             
   324886kB   848kB/s / Fetching revisions:Inserting stream:Estimate 113712/116014                   
   327077kB    34kB/s - Build phase:Building tree 42/710                                             
   Branched 1813 revision(s).  
   $ du -hs cloud-images/
   314M	cloud-images/

  However, if I do the same thing on a lucid system 
   $ bzr --version | head -n 1
   Bazaar (bzr) 2.1.4
   $ bzr branch lp:~ubuntu-on-ec2/live-build/cloud-images
   $ du -hs cloud-images
   $ du -hs cloud-images/
   52M     cloud-images/

  So I guess i have 2 issues:
   a.) why the "This transport does not update the working tree" message
   b.) why the 250M+ upload for "no revisions to push"
   c.) why am I do I waste 6X the space on oneiric that I would for the same thing on lucid.
