I have springpython 1.0.0 RC1 running on an Apache/Mod-WSGI installation.
The default policy of mod_wsgi is to restrict stdin/stdout/stderr as an application should not require to read/write on these filehandles.
As springpython uses amara (and amara uses 4suite-xml) the problematic part is
Ft/Xml/Sax.py", line 247
where 4suite-xml initializes a SaxPrinter with default filehandle sys.stdout.
Not really a direct springpython/4suite-xml/mod_wsgi problem :)
But it's one :)
Set "WSGIRestrictStdout Off" in the Apache central module config.
