Hi all,

I am running the connector with multiprocessing as outlined on [1]. In
my OpenERP database there is a certain module installed that indirectly
requires urllib3 from the Python standard library. The file
'connectionpool' from urllib3 needs the Queue/queue class from the
Python standard library and because of Python 2/3 issues it first tries
to import 'queue' before importing 'Queue'. However, the import finds a
'queue' class, namely the one from the connector. This in turn causes a
ValueError during the import as the exception trace below shows [2].
This problem seems to occur only in the connector, OpenERP itself is
running fine.
Has somebody already encountered this problem or do you have ideas for a
good solution? Or is it even a problem with the Python standard library?
There also is a similar question on help.openerp.com [3].
I mitigated this issue by patching urllib3/connectionpool.py from the
standard library, but this is not an optimal solution.

Best,
 Thomas.
