Running the command pitivi results to the following output:

Did you check that the mentioned file is actually an SVG file?  You
store might be broken in which case you would need to repair it.

I checked three different versions of pitivi – one rather old one,
current master and one on staging with a bunch of local GStreamer
updates – all three launched successfully.

Cheers

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.

Isn't there a per-package solution to this that basically means adding
librsvg to the package inputs?

Agreed; on the other hand it's not much more impractical than having to
propagate manually the icons, albeit harder to discover.  An easy
solution is to propagate librsvg, which I did in 47f0b3ad14.  I've also
updated Pitivi to its latest release in the following commit.

Closing,

Thanks!

Hello Josselin,

thanks for your solution it works.

This is definitely not user friendly and should be fixed. Is it possible to change the subject to something more appropriate?

Best regards
Christian Miller
