[PyMOL] Pymol segmentation fault

[Ian B. <ian...@ya...>]

Hi,

I'm having an issue trying to run various plugins in pymol (apbs and
autodock).  Whenever I select a button that should bring up a file browser
to choose a file (e.g. "Choose Externally generated pqr" in apbs) Pymol
exits with: Segmentation fault (core dumped).  Same thing happens when I go
to Help>About.  I can open and save files normally, and just about
everything else works.

I've tried this in pymol 1.1r2pre, where I can at least get the apbs plugin
window to open, as well as the 1.2 trunk from svn (downloaded and compiled
last week) which just crashes when I try to open the apbs window (I can
install autodock.py and the window opens, but it crashes when I try to
choose the location of files).  I'm guessing this is something to do with
the gui and tcl/tk, but don't have any idea how to troubleshoot (see the
catchsegv output below).  I'm running Ubuntu 9.10 on x86_64 and have  a
GeForce 8400M GS/PCI/SSE2 with the proprietory nvidia driver 185.18.36.

Does anyone have any thoughts?

Here is the backtrace portion from catchsegv:
