Description of problem:

When testing 526313 over ssh on shared box, I've noticed that 'modules' command in python interactive help probably executes more stuff than necessary, resulting in traceback in the case when no display is available (which is the case of ssh-ing to the box). I also tried to ssh there with -X to see what happens, which results in some gtk (I think) output one would not expect in this context. 


Version-Release number of selected component (if applicable):
python-2.6.2-7.el6.x86_64

How reproducible:
always

Steps to Reproduce:
1. ssh <rhel6 box> # I think it should be reproducible even in RHEL6 box in runlevel 3, but I have no such box
2. $ python
3. >>> help()
4. >>> modules abcd
  
Actual results:
help> modules abcd

Here is a list of matching modules.  Enter any module name to get more help.

RuntimeError: could not open display

Expected results:
no traceback

Additional info:
When you *have* a display, you can get something like this, which also does not seem really right: 
** (.:27993): WARNING **: Trying to register gtype 'WnckWindowState' as flags when in fact it is of type 'GEnum'

** (.:27993): WARNING **: Trying to register gtype 'WnckWindowActions' as flags when in fact it is of type 'GEnum'

** (.:27993): WARNING **: Trying to register gtype 'WnckWindowMoveResizeMask' as flags when in fact it is of type 'GEnum'

It seems this is more likely an issue of some misbehaving python package, but I've reported it to python because I'm not sure what the help() >>> modules actually executes.
