Problems with bzr.dev tonight

[Ian Clatworthy]

It looks like something has broken today in bzr.dev. This might be a
false alarm but I thought I'd raise it as:

* other people might see the same thing and wonder if it's just them
* I'm heading off for the day so I won't be looking into
  it any further tonight.

Here's the summary:

* ./bzr pull appeared to work fine pulling 2907 using 2906
* it's broken after that, either by 2907 or something earlier.

Lots of details below.

It might be completely unrelated but I was seeing a similar thing trying
to pull Robert's latest packs branch earlier this evening. If it's
relevant, ~/bzr is a shared repo.

Hmm. I remembered that I've got a separate copy of the pack stuff in
~/bzrpack - no shared repo this time.
