Hi,
As reported here:
http://code.google.com/p/pythonxy/issues/detail?id=232
this problem is happening with the new Enthougth Tool Suite plugin
shipped with the latest Python(x,y) beta version (v2.6.6.0beta1).
I've just fixed this issue by adding a new option in Spyder ("Ignore
PyQt API change errors") which is enabled by default:
http://code.google.com/p/spyderlib/source/detail?r=4fb9a89c6320719280b87b6583823cb9e7736432
So now, in Spyder development version (which may be installed easily
on any platform), this issue is fixed.
Cheers,
Pierre
