Hello all!

I've used Guix on Parabola GNU+Linux-libre to install Icecat, but I'm
having trouble running Icecat in the sandboxing tool Firejail [1]. The
problem is that whenever I start Icecat via firejail, the fonts are
completely broken and the browser only displays tofu in place of every
character. I'm sending some error messages as an attachment, which look
like they are related. In case the attachment doesn't make it through,
here is a sample:

> (/gnu/store/20622y5w8ixlh6zbrbzv5934wcshvi64-icecat-68.2.0-guix0-
> preview3/lib/icecat/.icecat-real:46):
> Pango-WARNING **: 13:17:17.854: scaled_font status is: file not found

Does anyone happen to have experience with a similar problem, or some
idea how it may be fixed? There's an open issue on Firejail's bug
tracker [2]. I think what I need to do with Icecat is to figure out
which files/directories it needs to access, and for Firejail it's to
figure out how to grant the access. Advice for either would be
appreciated.

Best wishes
