Bug Description

  affects bzr-hg
  status triaged
  importance medium

We seem to end up with an inconsistent delta in some situations during
fetch. An example of this is triggered by the xemacs repository:

bzrlib.errors.InconsistentDelta: An inconsistent delta was supplied
involving '<unknown>', 'hg:modules_ssample'
reason: Parent is not present in resulting inventory.

as also seen in http://launchpadlibrarian.net/40915075/vcs-imports-sphinx-trunk-log.txt. I'll attach the .b.zr.log from trying the fetch locally.

So I located the place of the exception here:
http://bazaar.launchpad.net/~bzr-pqm/bzr/bzr.dev/view/head:/bzrlib/inventory.py#L1775
But still I don't really understand the meaning... Is there a way to workaround this problem? Is there something with the Repository wrong... Maybe somebody can explain me in this exception in detail. Thanks.

I'm facing this bug attempting to import the Go repository by hand too, just with plain command line interaction with linear commits (no branching/merging/etc). It seems to be unrelated to the bzr-hg import system itself, but rather about the content in the repository somehow.

Actually, my problem *is* on bzr-hg. Even though I didn't use bzr-hg for this branch, the branch
contains a .hg directory as part of it (which was done precisely as a cheap workaround for
this bug), and bzr-hg was kicking in unintendedly.

Thanks to maxb over IRC for the hint.
