GWT crashes the Cajoler

As a quick status update on GWT emitting Caja, I am currently  
crashing the Cajoler.  I tried running a small test gadget through  
the Cajoler in order to get a list of concrete problems with cajoling  
GWT's current output.  I expected a long list of complaints, but  
unfortunately the GWT output is so unexpected that the Cajoler  
crashes before it can form a coherent complaint.

Here is the test gadget:

Here is the top of the stack trace; it looks like a problem with  
parsing the Javascript.

I went ahead and opened a Caja bug report about it:

http://code.google.com/p/google-caja/issues/detail?id=67&sort=-id


I know this is a vague bug report, but perhaps there are multiple  
issues involved, so I went ahead and posted the whole (but small)  
gadget.  Any technical issues that arise might be better posted to  
the issue's thread.
