Wrong MainWindow icon.

I specify application icon (via .rc file), it contains 4 images, all 32bpp: 16x16, 32x32, 48x48 and 256x256.

The icon for MainWindow should be 16x16, as it is with Qt 4.5.x. But, instead of that, icon of a larger size is taken and scaled down (and, of course, it looks really bad).
Compilers

Wrong icon assigned to Main Window
Steps to reproduce / test case
1. Create new Qt4 GUI Application: app

2. Take an app.ico file with several images in it (16x16, 32x32, 48x48, 256x256, all 32bpp)

3. app.rc file:
IDI_ICON1 ICON DISCARDABLE "app.ico"

4. app.pro file:
win32:RC_FILE = app.rc

5. Build & Run:
Instead of nice hand-made 16x16 icon there's a scaled down icon of a larger size
