Example file from Calc

Attached example file contains some autofiltered number values and an empty
cell.
When this column B is filtered for values that include 0 but not the (empty)
entry, the (empty) entry also gets checked.

Steps to reproduce:
    1. Open attached file
    2. Drop down the autofilter on column B
    3. Uncheck the values 3, 4 and (empty) so tha 0, 1 and 2 are checked
    4. Click OK and drop down the autofilter again

Actual results:
The (empty) value is checked.

Expected results:
(empty) should stay unchecked. The row with the empty cell in column B should
be visible.
