I've started seeing failures like this on WinXP when running mochitests on holly. Here is one failure:

The assertion happens at startup on all WinXP tests. It started happening between changesets df7b26e90378 and 7bacc9e903b0:

There are a number of changesets from Matt and nical there, so maybe you guys can help to narrow it down. If not, I can start pushing to try to narrow down the regression range.

I don't see this assertion anymore. This is the closest thing I can find:
