Hello Lily and Christian, This is unfortunately the usual gdk-pixbuf SVG loader not being found, since it is part of librsvg. Some details are described in [1] already, but to summarize: we need to propagate gdk-pixbuf so that the search-path GDK_PIXBUF_MODULE_FILE is properly set for the profile.
Hence, I can reproduce the issue with --8<---------------cut here---------------start------------->8--- guix shell --pure pitivi -- pitivi --8<---------------cut here---------------end--------------->8--- but the following launches pitivi properly (didn't check further) --8<---------------cut here---------------start------------->8--- guix shell --pure pitivi gdk-pixbuf hicolor-icon-theme adwaita-icon-theme -- pitivi --8<---------------cut here---------------end--------------->8--- I think it's very impractical that we have to do this for all packages that wish to load SVG files via gdk-pixbuf, because it's technical and not a concern that upstream developers document, since they don't encounter such behavior.
