Paolo, I would re-install Pyside.  Or even your entire Python distribution.
Something seems wrong with your installation because your "bad" file works
perfectly fine on my system.  In particular, all these missing attributes in
the layout and spacer classes seem to indicate a mismatch of some binaries
in your installation.  

It does seem the .ui files were processed by the correct uic utility, given
the comments in the generated .py files from that.  But the runtime Qt DLL's
just aren't supporting the required attributes somehow.

Hope this helps,
David
