Debian’s evince (/usr/bin/evince) is built with a GTK and the Guix’s emacs with another. Try: sudo apt install evince guix environment --pure --ad-hoc emacs emacs -q -f shell and type “/usr/bin/evince”. You should get an error: --8<---------------cut here---------------start------------->8--- (evince:19226): GLib-GIO-ERROR **: 02:24:21.012: No GSettings schemas are installed on the system Trace/breakpoint trap --8<---------------cut here---------------end--------------->8--- Compare with: guix environment --pure --ad-hoc emacs evince emacs -q -f shell and type “evince”. Then I do not have any error when I open the print dialog; but I have no setup for CUPS on my machine though. > --8<---------------cut here---------------start------------->8--- > $ evince& > [1] 22463 > jorge@jorge--inspiron-5570:~/unison/STJ/repos/usuários_arriscados_AD$ > (evince:22463): Gtk-WARNING **: 19:41:17.738: Theme parsing error: > gtk-keys.css:1:0: Failed to import: Error opening file > /gnu/store/gazmlv80882hgkdnfdzl50b4m8xxj1bz-gtk+-3.24.23/share/themes/Emacs/gtk-3.0/gtk-keys.css: > Permission denied > !

On my machine “(current-time-zone)” is correct but not “(current-time-zone nil "Europe/Paris")” which returns “(0 "CET")” instead of “(3600 "CET")”. Maybe it is a “bug” related to how Guix deals with timestamps because of reproducibility. I do not know. All the best, simon
