can't add a bank to the company

I'm using ocb-server 6.1

If I try to add a bank to the company, the browser hangs.

I have tried to do it in the company form (General Information tab -> Set banks accounts, or the Banks account tab).

I have also tried to create the bank account in Sales->Configuration->Address Book->Bank accounts.

In the three cases the browser hanged. After several tries, a bank account was created (even if the browser hanged) but didn't show up in the company form. I had to set the company_id in the res_partner_bank table in order for the bank account to show up in the company form.
