Right. As an interim solution, I would suggest this:
diff --git a/gnu/system.scm b/gnu/system.scm index ea6e9c1..2c1387e 100644 --- a/gnu/system.scm +++ b/gnu/system.scm @@ -511,6 +511,9 @@ export DBUS_FATAL_WARNINGS=0 # Allow Aspell to find dictionaries installed in the user profile. export ASPELL_CONF=\"dict-dir $HOME/.guix-profile/lib/aspell\" +# Allow GStreamer-based applications to find plugins. +export GST_PLUGIN_PATH=\"$HOME/.guix-profile/lib/gstreamer-1.0\" + if [ -n \"$BASH_VERSION\" -a -f /etc/bashrc ] then # Load Bash-specific initialization code.
This is inelegant, but better than broken software IMO.

Technically, populating <manifest-entry>’s ‘search-paths’ fields with search paths of the *run-time* dependencies may be difficult: We could get the information on run-time deps in the derivation that builds the manifest (via #:references-graph), but then that derivation would need to know all the possible search paths (that is, those of the build-time dependencies) so that it can select the subset of search paths corresponding to run-time dependencies. Needs more thought. Thanks, Ludo’.
