This seems to only affect devedition builds. I don't understand why yet.

[Florian Quèze [:florian]]

The patch I have in bug 1550034 will address this by disabling the test on RELEASE_OR_BETA builds.

Bug 1532596 covers the way to make the platform piece that the test depends on work on beta builds.
