Hi,
I had a quick look and it seems like it is a bug in libgtk-java. In
IconTheme.java, the native method gtk_icon_theme_load_icon has one
incorrect parameter. The signature should be
gtk_icon_theme_load_icon(Handle, String, int, int, Handle), but it is
gtk_icon_theme_load_icon(Handle, String, int, int, int[]).
In addition there is also a problem with loadIcon(String, int,
IconLookupFlags). It calls the Pixbuf constructor without checking if
the Handle received from gtk_icon_theme_load_icon is null. However,
according to the javadoc for GTK, null is returned if no icon is found.
Anyways, I am not very familiar with the java-gnome codebase, so I might
be wrong. :)
Regards,
Ismael
