PDF Text plugin does not appear to extract fulltext

It’s pdftotext version 0.12.4. And it’s working on the command line with this file.

Given that it’s the first document I’m uploading to a new Omeka install and the first plugin I’m adding to that install, I’m guessing that something about my setup isn’t working as planned, and I wonder where I can start on tracking down the problem. Maybe a bad permissions setting?

Is it possible to tell if the plugin as initiating any processes or if it’s not even getting that far? I don’t know what tools might exist on the server for diagnosing the problem.

Any ideas?

Thanks,
Ken
