Comment(by azrael):

 Pidgin doesn't follow the Freedesktop.org Icon Naming Spec:
 http://standards.freedesktop.org/icon-naming-spec/icon-naming-spec-
 latest.html

 Pidgin needs to rename the icons it installs to match the names in the
 icon-naming-spec. Then, it should use gtk_icon_theme_append_search_path()
 to append its directory to the end of the path (on GTK+ 2.4 and above) to
 provide the default icons if the user's theme doesn't define them. Then
 icons should be loaded with gtk_icon_theme_lookup_icon() on GTK+ 2.4 and
 above. (The fallback code can just load the icons from Pidgin's own
 directory.)
