Please give an actual (preferably small) testcase when reporting a bug.
I tried (lambda () (catch 'a (lambda () #!null) (lambda (x) x))) which 
worked.

This could be related to a recent check-in where I made the change I 
promised:
Basically eval and apply methds now specify 'throws Throwable', which means
primtive-throw and throw no longer need to wrap checked exceptions.
