an uncaught exception in the exception handler code.

<div>The failsafe code in dispatcher.rb is utterly obfuscated, one
of the guys in our team has patched it to return 500 properly, but that
hasn't been submitted back to rails core.</div>

As some kind of "last resource"...<br>
<br>
What about hacking a quick controller to respond with the<br>
offending codes and check how are they being handled?<br>
