I think a security issue is going on here. 
Mozilla is probably not firing the onerror event, because you use 'file:///'.
When using 'http://' the onerror gets fired (at least it does here).

I see this using LInux 2004101106.
I see this even when running from file://.

We should add this testcase once we have file:// mochitests.
