Sorry for the delay.

Changing status as I've not had any other duplicates - whilst it's critical for you, it's not for a wider problem for the whole project.


So from your trace:
 we're breaking whilst listing fonts. It's not one of the fonts that's being loaded. But probably one in your directory.

Ideally I want a list of all fonts on your system.
Removing the offending one should cause your system to start again, but I'd quite like to find what's breaking it so we can reproduce and fix properly.

Could you please list all the fonts on your system by attaching a file with the output of `fc-list` in it? Thanks!
