This doesn't seem to be a bug in "log", but it does indicate something
wrong with the branch.

This doesn't reproduce locally with:

bzr branch --no-tree --stacked ../other/branch test

(the 'test' branch has an appropriate last revision, and log, etc show
correctly.)

Note that just doing:
 bzr log -r-10..-1 lp:~launchpad-pqm/bzr-hg/broken

But "bzr log" does work, and shows the branch having 281 revisions.

Definitely something weird. Perhaps the fallback isn't properly found at
the time when it is looking up the revspec, but *is* found when it goes
to actually log the revisions?

beuno seems to be hitting this too:

beuno@beuno-laptop:~$

the branch.last_revision_info is plausible.

log works correctly on the branch and shows there is a 10th revision, but it isn't found by log or branch.

21:51 <sidnei> i think the key is 'It stacked on trunk, but has no extra revisions.' maybe?

fetching r10 from a local copy of this branch works.

here's a snapshot of the server-side branch. it does indeed have no packs of its own so it's possibly connected to being stacked with no local changes.

beuno has fixed his branch by pushing another revision, but I have another at lp:~mbp/convoy/test-stacking that is freshly pushed and can still reproduce this.

I guess this is going to only occur on RemoteBranch, and I suspect that is because it reimplements get_rev_id or something else reached by RevisionSpec_revno. The hpss log is attached.

See also the analysis in bug 785116 (a dupe).

I just got bitten by this with an ISD branch. It's a private branch, but can provide more details if needed.

Stefan (Chex) also just got bitten by this for an ISD branch.
