Well, I've had a few adventures while trying to reproduce your
problem, but I'm sorry to say that I haven't managed to shed any
light on this situation.
I dug out my PC and discovered that it had been infested by bugs!
Akkkkk! Bugs in my PC! Ewwwww.
Well, it wasn't all that bad, but I find it really funny that my
Windows laptop is buggy. Doh! Sort of the opposite of ironic. LOL.
I did some surfing to figure out what they are... turns out my PC
is infested with book lice. Little white specks crawling all over
my keyboard and LCD screen. So I spent yesterday afternoon trying
to rid my bug infestation from the PC and my storage cabinet.
I think I solved that problem anyway, but here is what happened
when I tried to reproduce yours:
I re-downloaded the 6.91 distribution and used it to write some
IPTC information. No problem. Then I deleted
inc/lib/Image/ExifTool/WritePhotoshop.pl from the temporary par
directory... Still no problem. It turns out that the
WritePhotoshop.pl file that is used is actually called 142cebc5.pm
(odd I know, but then I don't claim to know the inner workings of
the PAR module). Anyway, when I erased that file and tried again
it was just re-extracted automatically and everything worked fine
again. The only way I was able to break it was to specifically
corrupt this file, but then I got a different error message.
I was not able to do anything to generate the error you got.
So it is still a mystery, and all I can do is hope that 6.92 works
for you when it is released later in the week.
