saving UV layout: saving only selected UV's does unexpected things

Hi,

I’m having a problem with exporting the UV layout of a mesh I’m working on. It always saves all the faces, even if I unselect “all faces”. It doesn’t help if I have all the faces selected in the 3D view, and then only those UV’s selected I want to save, or have only the faces selected I’m interested in the 3D view, so that the UV editor only displays those UV’s.

And when I test with a cube, I get nothing when disabling the “all faces” option, even though I have something selected. If I disable the option, the entire map is properly saved.

Here’s the test blend file of the cube.

Is that option broken, or am I overlooking something?

Ah, thanks.

I thought I searched the forums well enough BTW, but I guess I didn’t.
