In popen2.py there is a class Popen3. It contains
a method _run_child().

-------
def _run_child(self, cmd):
    if type(cmd) == type(''):
        cmd = ['/bin/sh', '-c', cmd]
-------

I think that this test is attempting to find if the
"cmd" is not a list. Unfortunately <type 'unicode'>
does not get turned into a list. A better test may
be:

-----
def _run_child(self, cmd):
    if repr(type(cmd)) != "<type 'list'>"
        cmd = ['/bin/sh', '-c', cmd] 
-----

This problem shows up when creating commands from XML
files read by "xml.sax". Beta 2.2b1 still has this
code.

This would seem to have been fixed in revision 1.20 in CVS;
the check-in comment was:

Patch #487784: Support Unicode commands in popen3/4 handling
on UNIX.

Bugs that are already fixed are the easiest to close...

Ain't a time machine handy? :-)
