cannot be pickled
Status in OpenERP Web Client:
Triaged
Bug description:
Hi,
I attempted to install OpenERP 5.0.16 (as per the source from the
tarballs) on a fresh install of Ubuntu 10.04 LTS
The installation proceeds as normal, for both server and web client,
however, after the creation of the datrabase (and continueing to
install the base data), this error occurs after filling in the company
information.
a class that defines __slots__ without defining __getstate__ cannot be
pickled
