Serious problem with python-uno

[Ferenczi Viktor - Pannon Set <fviktor@ps.hu>]

Dear List,

I've installed OOo 2.0 successfully from backports.org. We have a backend 
python script converting documents between office formats using an OOo server 
process and the python-uno package. I've got this error and cannot find any 
useful reference to resolve this problem:

$ python
Python 2.3.5 (#2, Oct 16 2006, 19:19:48)
[GCC 3.3.5 (Debian 1:3.3.5-13)] on linux2
Type "help", "copyright", "credits" or "license" for more information.
>>> import uno
Traceback (most recent call last):
  File "<stdin>", line 1, in ?
  File "/usr/lib/python2.3/site-packages/uno.py", line 37, in ?
    import pyuno
SystemError: dynamic module not initialized properly

Anybody with the same problem or a solution?
