Summary: xml.sax second time file loading problem

Initial Comment:
Platform: windows 2000 SP2 (Pl)
Python version: Python 2.2 (#28, Dec 21 2001, 
12:21:22) [MSC 32 bit (Intel)] on win32

I have noticed strange problem while using the xml.sax 
module. When I run my application using python.exe 
everything is working fine, the error occures only when I 
try to execute my script using pythonw.exe.

The problematic code looks approximately like this (It's 
a PyQT based application btw):

parser = xml.sax.make_parser()
handler = MyAppDocumentHandler()
parser.setContentHandler(handler)
try:
   self.parser.parse(fileName)
   except IOError:
      QMessageBox.information(None,"MyApp","Sorry, 
problems occured while loading:\n"+fileName+"\n\nIO 
error:\n"+str(sys.exc_info()[1]))
      return FALSE
   except:
      print "Unhandled exception:", sys.exc_info()[0]
      QMessageBox.information(None,"MyApp","Sorry, 
problems occured while 
loading:\n"+fileName+"\n\nParser error:\n"+str
(sys.exc_info()[0]))
      return FALSE

The first time when I open the file everything works ok, 
the file is parsed, but when I try to open another file I 
catch the IOError [Errno 9] Bad file descriptor error. (The 
file location and everything else is ok.)
