Re: [PyMOL] Pymol segmentation fault

> Does anyone have any thoughts?

Two things to try that may or may not help:

1. Check if the problem persists when running pymol in single-threaded 
mode ("cmd.set('max_threads',1)").  libpthread in the trace might 
indicate that one of the libraries is having issues with multiple threads.

2. On Kubuntu 8.04.3 LTS x64, I can't reproduce the problem with 1.2 
from svn trunk.  This is using Tcl/Tk 8.4 (with pymol using it's own 
source build of python 2.4.2, which may or may not be relevant); so 
installing Tcl/Tk 8.4 instead of 8.5 (source or binary) might help 
resolve the problem, or at least eliminate one possible source.
