> these doctests aren't supposed to be run outside of the Launchpad test suite.

Right.

> it seems that if run with an older simplejson or something it doesn't trigger the problem.

We've had very similar simplejson/unicode related problems in the past. I think the newer ones work better but there's also some odd edgecase that Benji encountered in which he simply rebuilt simplejson (with the same version as before) to correct a test failure like this.

I'm triaging low because we do run the tests in Launchpad's test suite, and they are passing. Counterarguments welcome.
