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.
