:bufdo! bd! >> clear all buffers as you said.

Yesterday I had copied my session.vim file into ~/desktop so it seems it take care about history actions.

When I close Vim, no buffer is listed in buffers'list.
When I open Vim again, buffers'list contains my yesterday ~/desktop/sessions.vim which is not exsiting anymore.
