Comment 1 for bug 643994

I could solve the problem by making the following change in fetchmail.py file (line 157):

original:
res_id = email_tool.process_email(cr, uid, server.object_id.model, data[0][1], attach=server.attach, context=context)

new:
res_id = email_tool.process_email(cr, uid, server.object_id.model, msg, attach=server.attach, context=context)

Now I can process mails with my pop account....
