First up, thanks again to those who are helping.
I think I am getting a better handle on the problem.
I am using:
Ubuntu 12.10
Python 3.2.3
Qt 4.8.2
PyQt 4.9.3
I also have the ubuntu -dbg packages:
python3-dbg
python3-pyqt4-dbg
Do I need to run my program with python3-dbg?
I tried generating the core with the regular python3 and
the backtrace has thousands of lines with only a very few
mentioning anything about "No symbol table info available."
Like I said, the bt is thousands of lines. I have a feeling
that posting that here is not going to win me any friends.
Is the problem likely to be in the first few or last few lines,
or should I try to find someplace to paste the whole thing?
If I do need to run with the -dbg executable,
I don't understand why python3-dbg cannot import the PyQt4 modules...

[60323 refs]
>>> import PyQt4.QtCore

Also... The python3-pyqt4-dbg package seems to install to a different
location, so I tried inserting that dir on to sys.path with unexpected results.
$ python3-dbg

>>> PyQt4.__file__
'/usr/lib/python3/dist-packages/PyQt4/__init__.py'
[60337 refs]

I noticed that there was no __init__.py in
/usr/lib/debug/usr/lib/python3/dist-packages/PyQt4
so I added that and then...
$ python3-dbg

>>> PyQt4.__file__
'/usr/lib/debug/usr/lib/python3/dist-packages/PyQt4/__init__.py'
[60328 refs]
>>> import PyQt4.QtCore
Segmentation fault (core dumped)
Clearly, I am doing something wrong.
Any hints?
