In QtSDK 1.2, I opened my Qt project file created in Qt SDK 1.1, the Qt project can run on N900, but the icon can not be displayed, instead, a pure green icon was displayed.
I checked project setting, besides the "Icon to be displayed in Package Manager", the chosen icon was displayed properly. However, it was not displayed on N900 physical device. By the way, the icon is 64*64 pixels png file.
Thanks a lot.
