There is something like that here (
http://www.trolltech.com/products/qt/licenses/licensing/opensource)

"If you wish to use the Qt Open Source Edition, you must contribute all your
source code to the open source community in accordance with the
GPL<http://www.gnu.org/copyleft/gpl.html>when your application is
distributed."

"when your application is distributed". There are no licensing problems for
me.
I've just dowloaded the package and the lincense packaged is the GPL.
