  GStreamer | gst-python | Ver: HEAD CVS
           Summary: Silently overrides some functions of default module
                    optparse
           Product: GStreamer
           Version: HEAD CVS
          Platform: Other
        OS/Version: All
            Status: UNCONFIRMED
          Severity: normal
          Priority: Normal
         Component: gst-python
        AssignedTo: gstreamer-bugs at lists.sourceforge.net
        ReportedBy: kaeso at email.it
         QAContact: gstreamer-bugs at lists.sourceforge.net
     GNOME version: 2.15/2.16
   GNOME milestone: Unspecified


Please describe the problem:
gst-python seems to influence the behaviour of optparse.OptionParser() when
invoke with --help.
Doing and `import gst` in a python program using optparse will cause all help
text to be displayed like this:

Usage:
  istanbul [OPTION...] - GStreamer initialization

Help Options:
  -?, --help                      Show help options
  --help-all                      Show all help options
  --help-gst                      Show GStreamer Options

Application Options:

If you import gst after parsing the arguments, all works fine, displaying
original help text.
This bug is being worked around in many applications (like istanbul and
jokosher) just postponing `import gst`, but it would be better fixed directly
in gst-python 

Steps to reproduce:
1. import gst, optparse
2. implement optparse.OptionParser()
3. launch your app with --help
4. try again without importing gst to see the difference


Actual results:
steps 1,2,3: a fixed help text which says:

Usage:
  istanbul [OPTION...] - GStreamer initialization

Help Options:
  -?, --help                      Show help options
  --help-all                      Show all help options
  --help-gst                      Show GStreamer Options

Application Options:

Expected results:
the same as step 4: see my custom help text :).

Does this happen every time?
Yes
