[6.1] On the search view when press Clear button then default value of selection field does not cleared

[Jacara]

I'm testing openerp 6.1 stable version. I got this problem on web client.

On the search view when Clear button has pressed then default value of selection field does not cleared. They just changed to default value. It must be cleared. When user doesn't want to use default filters then they press Clear button. Right?

This is happens on only selection fields. On the normal many2one field default value has cleared by Clear button.
But on the gtkclient when i press Clear button then all search fields has cleared.
