Code completion hangs with Python 2.5.1

I'm using pydev 1.3.2 with Eclipse 3.2.2 on Windows XP.
With Python 2.5, when I type part of a name and press Ctrl+Space, I get the dropdown list for the code completion. When I try the same with Python 2.5.1, Eclipse hangs for a while. When it comes back, nothing at all has happened, especially no dropdown list has appeared.
I have reinstalled Python 2.5 and code completion works again. Reinstalled 2.5.1, code completion is broken again, so this seems pretty consistent.
Are you testing in an empty file with no tokens or do you have some sample code for it?
For me, it happens in a module as simple as this one:
class Test(object):
pass
Te
^
|
Put cursor here and press Ctrl+Space.
With Python 2.5, I get offered the dropdown list, with "Test" right at the top. With Python 2.5.1, Eclipse goes on vacation for a minute or so. When it comes back, it is without a result for the code completion.
I have found an entry in the error log. It seems that the Python process responsible for the code completion dies for some reason:

Can you run: c:\programme\python25\python.exe "C:\Programme\eclipse\plugins\org.python.pydev_1.3.2\PySrc\pycompletionserver.py" 52000 55352
in the cmd prompt and say if it gives some exception or some other output (in python 2.5.1)
Thanks,
Fabio
With Python 2.5 this gives:
pycompletionserver will start
pycompletionserver creating socket
pycompletionserver waiting for connection
The program doesn't return to the prompt and I can see a Python process running in the Taskmanager.
With Python 2.5.1 I get:
pycompletionserver will start
and then I'm back on the prompt. The Taskmanager shows a Python process for a moment which then disappears immediately. No exceptions are printed to the console. Is there another place to look for error messages (log file etc.)?
The problem seems to be gone with pydev 1.3.3.
Yeap, there were some optimizations done for the code-completion structure in 1.3.3 ;-)
Cheers,
Fabio
