Debian, Endless, and Ubuntu split the GTK+ 2 plugin process into a subpackage, so it might not be installed even if ENABLE_PLUGIN_PROCESS_GTK2 is true. All these distros are carrying a patch by Berto to hide GTK+ 2 plugins in this case. We recently split the GTK+ 2 plugin process into a subpackage on Fedora as well; it's installed by default for desktop users, but someone requested to be able to remove it for embedded devices that don't need it. We could add this patch downstream, but it'd be nice to upstream it instead so we don't have four distros all carrying the same patch.
