Extenstion simply crashed

[petrarca-arezzo]

I installed this extension and I simply get a crashed status. I have nothing special here, just a plain standard installation on KDE on Arch Linux.

Same problem on Cinnamon on Arch.

The problem lies that the plugin attempts to install, if not already installed, the htlmentities module (aside from the questionable idea of installing the module without consent). This doesn't work when the Python environment is managed externally.

The problem is easily solved by manually installing htlmentities and rebooting Ulauncher.
