bzr internal error on upgrade

[Bill Harris]

I use /etckeeper on Ubuntu 8.10 and, previously, on 8.04LTS, on two machines. Occasionally when upgrading software, I will get a complaint that the bzr working tree is out of date, and it will give me the opportunity to run `bzr update` before continuing. (While I use both Synaptic and apt-get, it has always happened when using Synaptic until today.) Up until today, that has worked.

Today, I ssh'd from one machine to the other and ran apt-get update. It gave me that same message. I opened a new terminal, ran `bzr update`, and it continued. Then it gave me the same error again, and I ran `bzr update` a second time. At that point, it said Bazaar had encountered an internal error I should report.

I've attached what I think is today's part of .bzr.log, and I've pasted the pertinent parts of the traceback from the terminal here, in case that helps:
