A nicer and  cleaner solution could be based  on the GIterator patch
to GLib:

This way you will be able to iterate through selected items by using
a  simple while()  loop,  and  get rid  of  the (orrible)  foreach()
callback pattern.

Furthermore, you  will ensure  binary compatibility with  other Gtk+
applications (since you won't modify any function signature).
