Single-click in Okular file dialog

[frisket]

I have Xubuntu 12.10 installed, and I set Single click to activate items in the File Manager settings. This works fine.

But Okular seems to use a different file manager in its file dialogs, and it is not picking up the single-click setting.

How do I set that?
