GalleryWildcardFilter doesn't support any value?

[strekazoid]

I'm trying to display only JPGs from the gallery on the phone:

@model: DocumentGalleryModel {
rootType: DocumentGallery.Image
properties: ["url"]
filter: GalleryWildcardFilter {
property: "fileName";
value: "*.jpg";
}
}@

This code gives me following error when running:

QML DocumentGalleryModel: The value of filter is unsupported
C:\sys\bin\gallery.exe exiting with 0 allocated cells, 519 handles

Also when trying with @_._@ value I'm getting the same error.

Using QtMobility.gallery 1.1 module.

Ok, in this documentation *.jpg is used as a filter value. I copied pasted the whole example from the doc, and have the same error:

Also, is there a way to request only thumbnails of the images, and not retrieve full images and then scale them down? The app performance is incredibly slow right now.
