[PyMOL] PyMol segmentation fault while starting from external python program

[Dmitriy I. B. <bry...@ms...>]

Launching PyMol form external python script will produce segmaentation 
fault.
For example starting "launch.py" from "/pymol/examples/launching"
 ----------------------------------------------
$ python launch.py
zsh: segmentation fault  python launch.py
 ----------------------------------------------
Crashes without even showing PyMol windows. 

Tried it on Fedora Core 1, Fedora Core 4, Mandriva 2005. The same story.
Different pythons and compiling different versions of PyMol does not change 
anything. 

It will launch PyMol windows if there is only
   import pymol
line. 

Adding
   pymol.finish_launching()
or
   from pymol import cmd
   cmd.load("$PYMOL_PATH/test/dat/pept.pdb")
will produce segmentation fault. With no windows shown. 

The same time if I'll try to debug step by step, let's say, "launch_demo.py" 
(from "/pymol/examples/launching")
 -------------------------------
pymol.finish_launching()
from pymol import cmd
cmd.load("$PYMOL_PATH/test/dat/pept.pdb")
cmd.show("sticks")
 -------------------------------
using IDLE. Everything will work. It starts windows, loads a file, changes 
to sticks...
Running it "python launch_demo.py" will wait for a second and return 
segmentation fault. 

If someone knows what's going on, please help me. 

 Thanks
