Ok, here goes...
I think the available references online are in error. From what I can gather, what we're calling the GW "2nd edition" is actually the 1st edition, and no true 2nd edition was printed. The cover art for the so-called 2nd edition is from the 1st edition artwork, not the recognizable 2e cover. Also, the ISBN for the 2e book is, in fact, the 1e number (1869893018). Since the book was published by GW in 1986 (October), it was clearly published prior to 2nd edition being released. So, I think all the confusion is simply over the book being mistakenly listed somewhere as the 2nd edition, and that info got repeated by various websites.
Here's the skinny on the 1e & 2e "core material" publication history:
1984
12001 - Paranoia 1st edition boxed set. English/West End Games/ISBN 0874310253
1986
010397 - Paranoia 1st edition HC book. English/Games Workshop/ISBN 1869893018
??????? - Paranoia 1st edition boxed set. French/Unknown Publisher/ISBN Unknown
1987
12001 - Paranoia 2nd edition boxed set. English/WEG/ISBN 0874310180
12000 - Paranoia 2nd edition SC book. English/WEG/ISBN 0874310636

?????? - Paranoia 2nd edition boxed set. German/Unknown Publisher/ISBN 3927903949
?????? - Paranoia 2nd edition SC book. German/Unknown Publisher/ISBN 3980185036
That's the best that I can come up with.
