It seems that the problem is due to this change made into callint.c:
2004-03-28 Stefan Monnier <monnier@iro.umontreal.ca>
* eval.c (Fcommandp): Simplify.
* data.c (Finteractive_form): Rename from Fsubr_interactive_form.
Extend to handle all kinds of functions.
* lisp.h (Finteractive_form): Declare.
* callint.c (Fcall_interactively): Use it.
It looks that the lisp object 'form' is not initialized in callint.c.
After I applied the following small patch the problem disappeared.
Sincerely,
David
