Hi Daniel, Hi Ludovic, I can reproduce the missing icons issue by running > guix shell --pure -f xournalpp-fix.scm -- xournalpp as suggested below. Wondering why the icons are not missing when I run xournalpp in my environment I discovered that > guix shell --pure gtk+ -f xournalpp-fix.scm -- xournalpp resolves this problem. Looking at your xournalpp-fix.scm file I wondered what the function modify-input exactly does (and how to add gtk+ to the append clause). I don't find neither documentation in the manuals nor code for it in a guix checkout (when I do a recursive grep in the source for guix or gnu modules the result is empty).
