Aha. Something like this works:

 (defun nic-error ()
   (let ((x 1))
     (error "MEH")))

 (defvar nic-args nil)

 (flet ((debug (&rest args)
          (setq nic-args args)))
   (condition-case err
       (nic-error)
     ((debug error) "blah")))

It seems a bit odd having to specify the debugger to capture the
backtrace.

I guess I could make a new condition-case like macro that did this
routinely.

Wouldn't it be better to just grab the backtrace whenever an error
occurs and put it in a global or push it on to a global list?
