Qt 4.7 SDK incorrect GTK style

[guiQt]

Just updated to 4.7 and now Qt Creator appears in an old style Gnome theme instead of Ambiance (default on my system Ubuntu 10.04).
Furthermore, new built applications show up with the same theme.
Previously built applications look as normal as before update.
Checked settings: GUI Style > Desktop Settings (Default).
Tried to reinstall. Nothing changed.
It's not my first update in Qt and I'm very very disappointed.
How can I fix this?

It seems to be an "SDK build issue":http://bugreports.qt.nokia.com/browse/QTBUG-13881

Yes. We have a new package ready. I believe we will make a short blog entry once it's out.

Good news! Thanks.
I hope in future releases we'll se:
