Loading cursor bug when using pyside on windows

I have python 3.3 + PySide 1.1.2 on my Windows XP. The code which is enough for the bug to show up:

import sys
from PySide import QtGui

app = QtGui.QApplication(sys.argv)

wid = QtGui.QWidget()
wid.resize(250, 150)
wid.setWindowTitle('Simple')
wid.show()

sys.exit(app.exec_())

So what is the bug? When I save it as "test.py" everything runs great, but there is unwanted console window. So I save it as "test.pyw" to run using pythonw (so there is no console window). The problem is that for like 15 sec no matter what I do, the cursor is the loading cursor. The screen is in attachment.

After about 15 sec the cursor returns back to normal. It can't be app loading because 1) it's very small 2) running it with python instead of pythonw doesn't show the loading cursor even for a while.

It's very annoying, I wanted to create few simple GUI tools for my company with pyside, but for end user such behaviour isn't good looking and I definetely don't want it. On linux there is no loading cursor as well, so it's paltform related issue.

Is it pyside thing or it needs forwarding to python devs?
