I realise you've already solved the problem, but I hope you find the

I've read the documentation for Image::Thumbnail (under ERRORS) and I
don't understand what it means. Good luck. I'd be inclined to check
what $t contains, though - maybe it's undef on error.
Secondly, you're using what's called indirect method syntax by saying
"new Image::Thumbnail(...)". This can cause subtle problems in your
programs, so I suggest you get into the habit of writing
"Image::Thumbnail->new(...)" instead. I realise you've just copied
the documentation - various CPAN modules get this wrong.
Finally, it's ages since I've generated thumbnails within Perl, but I
believe people nowadays recommend Imager (pure perl) or Image::Imlib2
