[6.1] base_crypt installation error

[Denis Karataev]

Hello!

When I try to install base_crypt module, I get the error:

Client Traceback (most recent call last):

TransactionRollbackError: could not serialize access due to concurrent update

I found the same bug https://bugs.launchpad.net/openobject-server/+bug/904839, but it regarded as duplicated, and linked to the bug with status Fix commited: https://bugs.launchpad.net/openerp-web/+bug/888425.

So I posted the new bug, because I want to pay attention to this problem again. I attached the video for better understanding. Hope to quick fix for it, because base_crypt module is very important. I think that plain text passwords isn't the best choise.
