Hi everybody!

First of all thanks for all the work you guys are doing for mat. Over time it has become one of my standard installs. Having said that, I have a questions about the latest version. We're in the process of upgrading our boxen from *buntu 16.04 LTS to 18.04 LTS. And as such, mat is (re)installed, together with its dependencies (python-mutagen python-pdfrw libimage-exiftool-perl gir1.2-poppler-0.18) Today, one of our users mentioned that the mat version on his newly installed system did not support PFDs any more. Checking, mat does indeed give a File format not supported.

Curious, I compared the mat install on a 16.04 (which works absolutely fine) with a 18.04 install and saw:

Since the only difference I can spot is the difference in mat version numbers (i.e. 0.6.1-2 vs 0.6.1-4) and the fact that pdf is no longer listed under mat -l I just wanted to make sure: Is support for pdf dropped in mat version 0.6.1-4, or should I be looking at a different cause for this?

Thanks in advance!
