Bug: Hang on subscripted access to request.subprocess_env.

| Greetings,
I think the following may be a bug in mod_python. I can't seem to find a
bug database or tracker for mod_python?
When subscripted access is used to access variable 'SCRIPT_FILENAME' in
the request.subprocess_env table/mapping, the code hangs.
The following snippet illustrates the problem.
# -=-=-=-=-=-=
def postreadrequesthandler(request):
request.add_common_vars()
value = request.subprocess_env['SCRIPT_FILENAME'] # This hangs
# value = request.subprocess_env.get('SCRIPT_FILENAME')# This works
return apache.OK
# -=-=-=-=-=-=
The strange thing is that the .get() access works fine: only the
subscript hangs?
The environment is
Apache: 2.0.59
ModPython: 3.2.10
Python: 2.4
OS: Windows Server 2003
If anyone is wondering about a use-case, I don't actually have one. I
was just iterating over the contents of the request.subprocess_env using
a for loop (code below), and found that the code hung when accessing
'SCRIPT_FILENAME', and not for any other variable.
# -=-=-=
d = {}
for sek in request.subprocess_env.keys():
d[sek] = request.subprocess_env[sek]
# -=-=-=
Regards,
Alan.

No time to investigate right now. I'll take a look tonight.
