Bug Description

I can easily repeat rhis failure with bzr 1.2 (on Linux) and bzr 1.3rc1 (on Windows). It's seems similar to bug #177874, but I encounter this when I try to upgrade one of my own branch, not bzr.dev. And then I found the same error for branch made from scratch.

Here's steps to reproduce:

C:\Temp\2>bzr init
C:\Temp\2>bzr info
Standalone tree (format: pack-0.92)
Location:
  branch root: .
C:\Temp\2>echo foo > spam
C:\Temp\2>bzr add
added spam
C:\Temp\2>bzr ci -m 1
Committing to: C:/Temp/2/
added spam
Committed revision 1.
C:\Temp\2>echo bar > spam
C:\Temp\2>bzr ci -m 2
Committing to: C:/Temp/2/
modified spam
Committed revision 2.
C:\Temp\2>echo boo > spam
C:\Temp\2>bzr ci -m 3
Committing to: C:/Temp/2/
modified spam
Committed revision 3.

if conversion fails, you can move this directory back to .bzr
if it succeeds, you can remove this directory if you wish

bzr: ERROR: Revision {('<email address hidden>',)} not present in "<bzrlib.knit.KnitGraphIndex object at

The important part is 3rd commit. With 1 or 2 commits in the branch upgrade succeeds.

Just checked: the same error with conversion from dirstate-tags format to rich-root-pack
or even simply rich-root.

I boiled down your test case to:
bzr init
echo foo > spam
bzr add
bzr ci -m 1
echo bar > spam
bzr ci -m 2
echo boo > spam
bzr ci -m 3
bzr upgrade --rich-root-pack

And it succeeds with me.

However, if I switch it to commit 6 times, it fails again. I almost wonder if it isn't failing somewhere else, and then we are getting a second exception while doing cleanup, etc.
Specifically, because after it has failed, if I do "bzr log" I get the same exception, and it is because .bzr/repository/* is mostly empty because of the failed conversion (.bzr/repository.backup still has the old repository).
