[PyMOL] Segmentation fault

Dear all,

I started experiencing segmentation fault on a pymol that I had installed
through the omnia channel on conda.

Then, I decided to install from scratch using this recipe:
https://pymolwiki.org/index.php/Linux_Install#Get_latest_source_from_SVN

Still getting the segmentation fault, so maybe something changed in my
system and it's conflicting with?

The segmentation fault is not on launching PyMOL, but rather when I do
stuff: loading a PDB file, building a fragment. Like this:

```
./pymol: line 3: 28505 Segmentation fault      "/usr/bin/python2.7"
"/data/joao/maindisk/software/pymol-svn/modules/pymol/__init__.py" "$@"
```

Curiously, when I load a 1.740 session (.pse file I had saved), it works
(no segmentation fault), I can even perform commands like select and stuff,
and they work. If I load a more recent 1.803 session, it also seg faults:

```
 Executive: Loading version 1.803 session...
./pymol: line 3: 29221 Segmentation fault      "/usr/bin/python2.7"
"/data/joao/maindisk/software/pymol-svn/modules/pymol/__init__.py" "$@"
```

Any clues? Am I doing something wrong?

Thanks,
João
