"bzr: ERROR: exceptions.KeyError" during update on svn lightweight checkout

[Wesley J. Landaker]

When doing an update in a lightweight checkout, I get a KeyError. This is different than #190843, but might have a similar fix.

This is with the very latest bzr.dev and bzr-svn updated a few minutes ago:

$ bzr up

 milestone 0.4.11
 status confirmed

There's already a test in the testsuite for this.

[Jelmer Vernooij (jelmer)]

Fixed committed to the 0.4 branch. Please reopen if you can still reproduce this with your branch.

[Wesley J. Landaker (wjl)]

Everything seems fine in the repository where I original saw this error. I'm not seeing it anymore with bzr 1.9 and bzr 0.4.15.

But I reported a different one in #304134 that affects a different repository! =)
