It's quite a hack, and hence not very workable if anything changes in the GTK world.

In previous posts there were an idea that said something like "working with Gnome devs". This sound pretty nice to me, because:
- If I want to make it work every app on my Kde distro, for some apps I'll have to use file dialogs that are not native... this for an advanced user is nothing, but for average user is quite something weird... 2 clicks and all that stuff
- it is the same thing for Kde apps on a Gnome environment? if it is, then they're having the same problem...
It's something of making feel the system consistent... Kde & Gnome should work together in fixing this for the consistency of their desktops

Come to think... I've never seen a Dolphin file dialog in a Gtk environement...

Because Qt has a Gtk platform integration plugin, and KDE applications are written in Qt, it is fully possible for KDE applications to style themselves using Gtk - which includes the file picker I believe. As far as I know, it is not possible to achieve the same for Gtk applications under KDE though - the Oxygen-Gtk theme helps quite a bit though (for the general appearance, icons, etc).

I've resorted to using Chrome which not only uses KDE file dialogs, but it also uses KDE's file/mime associations.

I would guess Chrome uses Gnome's GTK file dialogs, so again, how hard can it be to have Firefox use the right dialogs based on which DE is running? I mean, if Chrome can do it...
