Virtually all instances come immediately after 'NS_ENSURE_TRUE(domDoc && target) failed' (bug 1183845). Looking at the tests again they all seem to correlate as well.

Inspecting the code we can see the warning is generated by inspecting the rv of a call to |GetEventAndTarget| which is where the warning is emitted in bug 1183845.
