[DL] String additions to 'grilo.master'

[GNOME Status Pages <noreply gnome org>]

This is an automatic notification from status generation scripts on:
https://l10n.gnome.org.

There have been following string additions to module 'grilo.master':

+ "Could not resolve media for URI “%s”"
    + "Media has no “id”, cannot remove"
    + "Metadata key “%s” already registered in different format"
    + "Metadata key “%s” cannot be registered"
    + "Plugin configuration does not contain “plugin-id” reference"
    + "Plugin not found: “%s”"
    + "Plugin “%s” already exists"
    + "Plugin “%s” is already loaded"
    + "Plugin “%s” not available"
    + "Source with id “%s” was not found"

Note that this doesn't directly indicate a string freeze break, but it
might be worth investigating.
