Yes. One of you is missing the source code ;)

 From "What is Copyleft?"
(http://www.fsf.org/licensing/essays/copyleft.html)

"To copyleft a program, we first state that it is copyrighted; then we
add distribution terms, which are a legal instrument that gives
everyone the rights to use, modify, and redistribute the program's
code or any program derived from it but only if the distribution terms
are unchanged. Thus, THE CODE AND THE FREEDOMS BECOME LEGALLY
INSEPARABLE" [Emphasis mine]

 From the FSF GPL Howto:
(http://www.fsf.org/licensing/licenses/gpl-howto.html)

"Whichever license you plan to use, THE PROCESS INVOLVES ADDING TWO
ELEMENTS TO EACH SOURCE FILE of your program: a copyright notice (such
as “Copyright 1999 Terry Jones”), and a statement of copying
permission, saying that the program is distributed under the terms of
the GNU General Public License (or the Lesser GPL)." [Emphasis mine]

IANAL etc etc but these both suggest that the source code is where the
copyright and license REALLY reside, hence no actual source == no
actual license regardless of whether the distributor TOLD you a binary
was GPL, or even supplied you with the text of the GPL to go with it.
