Python 2.7 crashes in pymol application

Question

I am new to ubuntu, please forgive me for any logical comments.

While attempting to load a pdb file in pymol, I will get a system crash report:

ProblemType: Crash
Architecture: amd64
CrashCounter: 1
CurrentDesktop: Unity
DistroRelease: Ubuntu 14.04
ExecutablePath: /usr/bin/python2.7
ExecutableTimestamp: 1434999065
ProcCmdline: python2.7 -m pymol.__init__
ProcCwd: /home/administrator
ProcEnviron:
 LANGUAGE=en_SG:en
 TERM=xterm
 PATH=(custom, no user)
 XDG_RUNTIME_DIR=<set>
 LANG=en_SG.UTF-8
 SHELL=/bin/bash

I have tried a few methods e.g. installing nvidia drivers; upgrading to the latest kernel; reinstalling python2.7 and pymol. But i can't seem to fix this issue.

These are my systems information:

Please advise. Thank you.

Pymol starts to work fine without python crash after i revert the nvidia driver back to an older version 304.131. Installed through Ubuntu repository:

sudo apt-get install nvidia-current

You can also specific a version to install, e.g.
sudo apt-get install nvidia-331
sudo apt-get install nvidia-340 

Hope these helps.
