Yes that's what we do in the new hildon-desktop code (see https://stage.maemo.org/svn/maemo/projects/haf/trunk/hildon-desktop/). Unfortunately it doesn't solve all the problems. Say plugin foo links against gtkhtml, then the types for gtkhtml get registered statically, then registered again when the applet is reloaded. -- Johan Bilien [EMAIL PROTECTED] ___ maemo-developers mailing list maemo-developers@maemo.org https://maemo.org/mailman/listinfo/maemo-developers

Is this a bug? May be I miss understand the problem? However it seems that this function isn't called when switching off plugins or just doesn't unload plugins from memory. Is this a bug or have I missed something? How should it be done properly? Thank you.

Hi, sorry for the very late answer, home is not dlclosing the plugins, because many plugins (including the shipped ones) register GType. dlclosing the re-opening them results in them trying to re-register the types, even though glib already knows about them.
