I was trying to be creative by loading BrowserID on the fly, but that won't work. Fixed! https://github.com/mozilla/zamboni/commit/0a10cfb56491bca9ff151ffd8fa8213e1d5cddec Krupa claims it sometimes randomly happened before my changes, but for now we'll close it.
I cannot reproduce this issue anymore.
