I thought that it may be useful for people to keep this in mind just in 
case (one could have experienced a similar problem and have an idea on

I posted this message for PyQt users *information* only: that's why I 
mentioned that I've posted on the matplotlib mailing-list too (which was 
obviously the real "bug report").
