[Opera-Linux] making Opera use the native GTK file chooser

[Liviu Andronic]

Hello everyone,

The latest "Snapshot extravaganza"
(http://my.opera.com/desktopteam/blog/2007/09/28/snapshot-extravaganza),
also known as Opera 9.50 Alpha Build 1600, provides the following
improvement: "(UNIX) When running Gnome, Opera will now use the native
GTK file chooser when opening and saving files (w00t).

I am extremely interested in this feature when using Xfce on Gentoo.
However, in Xfce, Opera displays the plain old qt3 file chooser upon
hitting <ctrl>s .

Does anyone know how can I make Opera use the native GTK file chooser?

Regards,
Liviu
