Inpsection of CLOS objects

I am unable to inspect a CLOS instance. Everytime that I try it, I get
the following error message in the inspector:
Trap: the subscript given to the ZL:AR-1 instruction, 21, on
#<CLOS-INTERNALS::CLASS-INSTANCE-INFORMATION PHYSOBJ 114066063> was
beyond the length, 19.
This doesn't happen on any of the simple cases I have been able to
construct. You should send a copy of the backtrace (the first few frames,
anyway) and the DEFCLASS for a simple test case which makes this fail to
Customer-Reports@Symbolics.COM (and not SLUG, unless they don't help you).
This is simplest if you use the c-M [Send Bug Mail] debugger command.
If possible, you should include the output of DESCRIBE of the object as
well. One way to do this is to store the object in some variable (e.g.,
*MY-PHYSOBJ*) in its INITIALIZE-INSTANCE :AFTER method, and then type
m-0 m-X Evaluate Into Buffer <return>
before sending the mail. This will put the DESCRIBE output into your mail.
