Remote corruption issue, linked to thin pack code?

Hi *,

This one sounds fairly similar to

  http://thread.gmane.org/gmane.comp.version-control.git/123244/

which was never resolved.

Jonas reported repo corruption on IRC along the lines of

  $ make gitpush
  cd dist && git push ssh://<user>@eloxoph.com/repos/mainrepo/bla.git master
   
    -  W e l c o m e   t o   E L O X O P H  -
               friendly landlord

  <user>@eloxoph.com's password:

  Delta compression using up to 2 threads.
  Compressing objects: 100% (132/132), done.
  Writing objects: 100% (133/133), 1.01 MiB, done.

  fatal: pack has 114 unresolved deltas

   ! [remote rejected] master -> master (n/a (unpacker error))
  error: failed to push some refs to 'ssh://<user>@eloxoph.com/repos/mainrepo/bla.git'
  make: *** [gitpush] Error 1

The respective repos show no errors with git-fsck.  Jonas kindly
provides a download link for both:

  http://eloxoph.com/localrepo.zip
  http://eloxoph.com/remoterepo.zip

Versions are 1.7.2.1 locally and 1.5.4.3 remotely.

Beware, there are hooks in both.  Disabling them, however, only
changes the error slightly:

  [...]
  Total 133 (delta 118), reused 0 (delta 0)
  fatal: pack has 114 unresolved deltas
  error: unpack failed: index-pack abnormal exit
  To ssh://mainrepo@xxxxxxxxxxx/repos/mainrepo/bla.git
   ! [remote rejected] master -> master (n/a (unpacker error))
  error: failed to push some refs to 'ssh://mainrepo@xxxxxxxxxxx/repos/mainrepo/bla.git'
  make: *** [gitpush] Error 1

What's even stranger is that fetching from the repo is also not
possible:

  fatal: git-upload-pack: cannot find object e28ae6b61c384732c506544626c5083557dd2d75:
  fatal: The remote end hung up unexpectedly

despite the object being there.

What's also strange is that while there is a temporary pack inside
objects/, I get

  $ git index-pack --stdin < objects/tmp_pack_oEUkIc
  fatal: pack has 114 unresolved deltas
  $ git index-pack --fix-thin -v --stdin < objects/tmp_pack_oEUkIc
  Receiving objects: 100% (133/133), 1.01 MiB, done.
  Resolving deltas: 100% (118/118), completed with 63 local objects.
  pack    061120577b0a1fec7ba636d6e3162f95f83543aa

So it seems the remote side got a thin pack and can't cope.  But
a4503a1 (Make --no-thin the default in git-push to save server
resources, 2007-09-09), merged way back in 1.5.3.2, claims to enable
--no-thin all the time.  So how did a thin pack get there?

Any ideas?
