First off, I am running Qt Creator under Ubuntu 11.10. I understand that Qt Creator is warrantied up to 11.04, but from other posts regarding installing it via sudo to get around the gtk errors, I have been using it for a bit under this environment.
From the About Qt Creator... menu item:
Qt Creator 2.4.1
Based on Qt 4.7.4 (32 bit)
Built on Jan 25 2012 at 11:24:30

Even in this recent version, dragging a ListView from the 'Components Symbian' section of the Library crashes the application. Doing the same from the 'Qt Quick - Views' works fine.
