Comment 10 for bug 599299

* the first filter action very often (allways?) after login fails
** workaround: click back and filter again
** sometimes also this

** same workaround: click back and filter again

after switching from simple query to advanced the same error occures ONCE again

IMPORTANT - IMHO this happens only once after restart of the openerp web-client
Can logout and login, close firefox - everythink works fine

special problematic form : my current tasks
first query fails
/error/HTTP_INTERNAL_SERVER_ERROR.html.var
back + require - works
click edit of one line
enter some text into Information tab - notes + save
