Summary: A problem with exceptions and the client-server mechanism

Initial Comment:
open IDLEfork.
then type in the shell window:
import re
re.compile("[a-+]")

The shell window writes:

Traceback (most recent call last):
  File "<pyshell#1>", line 1, in -toplevel-
    re.compile("[a-+]")
  File "/usr/lib/python2.2/sre.py", line 178, in compile
    return _compile(pattern, flags)
  File "/usr/lib/python2.2/sre.py", line 228, in _compile
    raise error, v # invalid expression

and then gets stuck. In the xterm, this is written:

Exception in Tkinter callback
Traceback (most recent call last):
  File "/usr/lib/python2.2/lib-tk/Tkinter.py", line
1292, in __call__
    return apply(self.func, args)
  File "/usr/lib/python2.2/lib-tk/Tkinter.py", line
436, in callit
    apply(func, args)
  File "./PyShell.py", line 421, in poll_subprocess
    etype = eval(mod + '.' + name)
  File "<string>", line 0, in ?
NameError: name 'sre_constants' is not defined

I'm using Python 2.2.1 on Debian woody.
