Good, I thought the problem might have something to do with the fact
that the objects in the prototype slot were made by allocate-instance.
Exploring a little further, I don't think it's has anything to do with
the inspector. It seems like it is related to the CLX classes.
Here's an example of what I'm talking about:
* (pcl::allocate-instance (pcl:class-of (make-instance 'xlib:drawable)))
Unable to display error condition
Restarts:
0: [ABORT] Return to Top-Level.
Debug (type H for help)
("DEFMETHOD SLOT-UNBOUND (T T T)" #<unavailable-arg> #<unavailable-arg>
#<unavailable-arg> #<error printing object> ...)
0]
Note that the following works fine.:
* (defclass foo () ())
#<STANDARD-CLASS FOO {482BF90D}>
* (pcl::allocate-instance (pcl:class-of (make-instance 'foo)))
#<FOO {480AAEC5}>
*
BTW, this is not a recently introduced problem --- I checked a Lisp
from May of 2000 and it also failed.
