Branching a stacked branch from Launchpad gives ErrorFromSmartServer: Error received from smart server: ('NoSuchRevision',)

After updating my local branches, I now get:

/home/tim/.bazaar/plugins/loom/revspec.py:64: DeprecationWarning: Modifying SPEC_TYPES was deprecated in version 1.12.
  SPEC_TYPES.append(RevisionSpecThread)

Branching over SFTP worked.

That now looks like one of our known bugs; however, it shouldn't be
happening if you had been pushing with the bzr version you said you had
(and you should have been getting this error from the start).

Are you sure you were using the packaged bzr?

I agree with Robert:

 - the NoSuchRevision error looks like bug 360791
 - the AbsentContentFactory error looks like bug 354036, which should be fixed by the version client you are using. Do you have a .bzr.log with -Dhpss trace of that push?

Here is the .bzr.log for the push that made the broken branch.

Yes I am using the version from the PPA, and yes it should have had the fix.

Just did a test with the ubunet guys, and they where using bzr nightly, as am I, when they push a branch and I try to branch it, I also get:

Last interesting bits of .bzr.log are:

I am promoting this to critical, because we now have *no* options. 1.13 creates broken branches, and newer versions don't work.

I also got this error last week, using bzr-nightly to push the branches.

Bjorn: which error? This bug report is confusing, as several distinct issues have been mentioned.

Please direct all reports and comments of the "ErrorFromSmartServer: Error received from smart server: ('NoSuchRevision',)" problems to bug 360791 (or if you think it is something else, file a new bug).

This bug is was orginally about a NoSuchRevision error that Tim got, but then an unexplained AbsentContentFactory error occurred too. The NoSuchRevision is explicable; Tim's report here is entirely consistent with bug 360791, so I'm going to close this bug as a duplicate of that one.

The AbsentContentFactory error is concerning, as it is apparently not bug 354036. I don't yet have any idea what the cause there is. I'll open a new bug report to track this. (I could repurpose this bug but I think making a new one will be less confusing as it will be clear which issue it is tracking.) The new bug is bug 369596.

Bjorn: please followup with your bug's details to whatever is the appropriate bug.

Tim: please look at bug 369596.

I was referring to the NoRevisionError that Tim got. Here's the
traceback I got:

    https://bugs.edge.launchpad.net/bzr/+bug/360791

It certainly sounds like bug 360791, since I getting this error on my
laptop, where it worked fine on my desktop (which had an up to date copy
of the stacked-on branch in the repo).
