    thumbnail: Fix a code path where the mutex is never unlocked
    
    Fix one unusual code path where the GnomeDesktopThumbnailFactory’s mutex
    is not unlocked before the function returns. As well as the usual
    deadlock issues, this would lead to an abort on shutdown with recent
    GLib changes, as g_mutex_clear() would be called on the locked mutex,
    which GLib now (correctly) complains about.
