So reassigning.

Concerning the urxvt failure, this is due to the fact that firejail
blacklists Perl for security reasons and urxvt needs Perl modules.
As a workaround, firejail should also blacklist rxvt in this case,
so that glib won't see it and won't try to run it (so it will run
xterm instead). I've submitted a pull request for firejail:

and also reported a bug for Debian:
