Please Add x11-themes/gtk-engines to DEPEND of media-sound/grip (gnome_segv2:13042): Gtk-WARNING **: module_path XXXX "clearlooks", XXXX: displaies error message by japanese, perhaps "there is no theme-engine".
Don't restrict bugs without any reason. Just leave the checkboxes alone.
Gnome team please advise about GTK+.
Sounds like they have a theme selected but no engine for that theme.
I couldn't find a single mention of clearlooks in grip sources, and it worked fine here without gtk-engines installed. Closing as WORKSFORME.
