Comment # 8 on bug 1016612 from Stefan Hundhammer

Antonio, lnussel told me you are one of our few remaining KDE experts here.

I know that you can override the default file dialogs in Qt with a desktop
environment's specific file dialogs. That must have happened here, but only
partly; the "load file" dialog seems to be overridden correctly, the "save
file" dialog not. There are still changes, but mostly it's the default Qt file
dialog, but it doesn't seem to find most of its icons anymore.

And for "root" there is no override at all, and everything seems to work
correctly.
