Machine: Sun SparcStation 1 w. 16 MB of memory
OS:	 SunOS Release 4.0.3c (NGS) #8: Mon Mar 5 02:05:01 EET 1990
Emacs:	 GNU Emacs 18.55.3 of Thu Dec 14 1989 on ngs.fi (berkeley-unix)

Error message:
Wrong type argument: natnump #(EMACS BUG: ILLEGAL DATATYPE (#o37777777701)  

I did not get the rest of the error message, but it seemed to continue
(across the window border).

What I did:
         I was reading new mail with mh-e
	 About 30 new messages where shown as {+inbox/unseen}
	 Most of the messages were marked to be deleted or refiled
	 I hit x, mh-execute-commands

What happened:
         The error message was displayed on the message line.
	 Most or all of the messages marked so where NOT refiled or deleted.
	 All refile and deletion marks were lost.

Repeat by:
         I couldn't.  So I think this just might be a more or less
	 nondeterministic problem.  In fact, I am still using the same
	 incarnation of emacs with no problems.

Further information:
	 As I do NOT read this mailing list regularly, please contact
	 me with mail if you want to know anything more.
