Not solved yet; but setting the same script up as a CGI instead
(i.e. copying into /cgi-bin/), it works fine; whatever the problem is
it's definitely caused by running under mod_perl.  

And now that I'm not changing the script so often, I see that it seems
to always (nearly always?) run correctly the first time after I change
it, and after that it mostly finds null EXIF data.  I see a very
*very* rare case where it comes up with the right data, so it's not
100.00% failure on reload, but it's close. 

Still looking for clues!
