Summary:  Fatal Python error: Interpreter not initialized 

Initial Comment:
When running 'bzr status' on Ubuntu 5.10 with python
2.4.2, I came across the error:
Fatal Python error: Interpreter not initialized
(version mismatch?)
Aborted

The bzr code in question has a __del__ method which
when invoked (eventually) imports socket (which imports
_socket), causing everything to fall over in a heap.

A backtrace is available at http://pastebin.com/399461

Feedback in #bzr indicated that I was triggering this code:
http://pastebin.com/399491 and also something similar to
http://mail.python.org/pipermail/python-dev/2003-September/038151.html
Another example that triggers it is
http://mail.python.org/pipermail/python-dev/2003-November/040188.html
It's all a stock breezy system, no external modules, and bzr
is retrieved from running:
 rsync -av bazaar-ng.org::bazaar-ng/bzr/bzr.dev .
I was using the latest revision at the time this happened.

Also, where is the bzr code and what version are you running?

Are there any other extension modules in the system that are
not provided with python?  When you went into gdb did it
print a long list of dynamic modules loaded?  Can you
provide that info too?

I'm guessing this is a memory overwrite which can happen
with poorly behaved C extension modules.  You could try
running python under valgrind and see what it reports.
