Gtk-CRITICAL error when attempting to install Qt

Wow, that is a really annoying bug they have there:-(
Try switching the Qt4 theme using qt-config (no idea where that is included in ubuntu) or just switch the GTK theme to one not provided by canonical. That might already work around the problem. Let's hope ubuntu fixes this soon!

Hi,
I'm having a similar problem when trying to install Qt on ubuntu 11.10. I tried on unity-2d and xubuntu desktops. The installer asks for type of installation (standard or custom), folder to install and then the computer almost hangs for several minutes. The installer still runs (the task bar icon is present) but when I click on it the computer hangs for several minutes, and nothing happens. When I run from the command line I get several identical error messages "Gtk_CRITICAL: IA_gtk_widgetstyle assertion GTK_IS_WIDGET".
How do you change the QT4 theme using qt-config?
I just noticed that Ubuntu software centre offers the option to install Qt-creator (and qt-others). I will try this route and see if I am successful.
EDITED
I can confirm that installation via ubuntu software centre was successful, the computer didn't hang up during the installation and the QtCreator program starts fine. -

The same problem!! tried every trick on the book! nothing worked (I'm running Ubuntu 12.04 :( )
And tried that version on the software Center !! Well It's not that similar to the one I used on MAC or on Windows, and has loads of errors especially when "compiling" (to be fair; couldn't understand the errors given though the "code" is 101 % correct)
I see that it'd started about a year ago, Linux didn't fix it; well !! Can we see an effort from Qt Team to fix that bug? If so, anytime sooner ?!! :( -
I am on Ubuntu 12.04 ./QtSdk-offline-linux-x86_64-v1.2.1.run -style motif works fine for me. Without the style argument my computer freezes
