maya.standalone.initialize() hangs forever

Steps to repeat:

gfixler@gigabox:/autodesk/maya2012-x64/bin$ ./mayapy
Python 2.6.4 (r264:75706, Nov  3 2009, 14:09:42) 
[GCC 4.1.2 20070626 (Red Hat 4.1.2-14)] on linux2
Type "help", "copyright", "credits" or "license" for more information.
>>> import maya.standalone
>>> maya.standalone.initialize() # this hangs until I ^C
^CResult: untitled
Fatal Error. Attempting to save in /usr/tmp/gfixler.20120908.1953.ma
gfixler@gigabox:/autodesk/maya2012-x64/bin$

I think it's a library path issue of some sort, but I don't know how to find out.

I figured out the issue.

In trying to solve this I learned about python -m trace --trace script.py, and also a bit about pdb, a Python debugger. I tied these together by calling a trace on a file containing this:

pdb.run(maya.standalone.initialize(), globals(), locals())

I don't know if that was using either incorrectly, or overkill (trace alone was hanging after printing out a tremendous amount of information, which redirected into a file yielded nothing useful), but after hitting n (next) and s (step) followed by hundreds of enter keypresses in pdb got me nowhere, on a whim I typed help and got a help menu. I decided to try the listed EOF command, and it ran until it crashed with a message about being unable to load the commandPort. I remembered I set that value to autoload (Preferences window, Applications section) last week while fighting with nose, and apparently that was causing it to hang on a bad entry (":12345"), with absolutely no messages about anything. I opened UI Maya, deleted that preference, and now mayapy initializes fine. Phwew.
