COM freethreaded mode bug?

[mic]

I enclose simple example of that error:

import sys
sys.coinit_flags=0  #if this one is commented out everything works fine
from win32com.client import Dispatch
ie = Dispatch('InternetExplorer.Application')
ie.Navigate('http://www.creatix.de/support/frames.html')
while ie.Busy == True:
    pass
print ie.Document.all.length
print ie.Document.images.length
print ie.Document.frames.length #this is the main source of evil :)
