Here's a puzzler: --title req'd when run by root
Here's a puzzler. I have a bash script that creates ebooks by running ebook-convert from the command line, either by the user or by root as result of a web form submission. It was working fine until I removed the --title option. Now it still works fine when run by the user, but the ebook-convert command fails when run by root as the result of the web form submit. As far as I can tell, the only difference is that I removed the --title option. When I put it back with a static --title=foo, both user and root work fine.
