Filter editor problems (unable to reapply filters)

I encountered several (maybe related) problems with the filter editor.

System: Ubuntu 9.04, Inkscape 0.47pre0 r21549, built Jun 12 2009,

Correct behavior:

First start inkscape, draw a box, apply the black outline filter to the box (black outline is correctly applied) and open the filter editor. The black outline filter is listed in the editor and the checkmark is checked.

Close inkscape.

Bug1:

Start inkscape, draw a box, open the filter editor, select the black outline filter from the menu (black outline filter is correctly applied', In the filter editor, the black outline filter name is now called 'filter'# (random number). The checkbox is also not check while the filter is applied. To fix this click the checkbox (this will activate the checkbox and the filter will still be applied).

Applying another filter will rename the black outline filter name (filter#) to its default 'black outline' name.

Bug2 (serious):

In the filter editor, select the black outline filter entry when it is applied to the object (checkmarked or not checkmarked as described in the situation above). Richt-click on the filter name and select remove. The filter is removed from the filter editor en the effect is removed from the object. Now re-apply the black outline filter (or any other filter) to the same object via the filter menu and the filter will not be applied to the object nor will it be displayed in the filter editor.

So, once an active filter is removed, new filters can not be applied to that object. The only way is to remove that object and redraw it. First the active filter needs to be deslected (by first activating the checkbox and than deactivating the checkbox in front of the filter name) and than the filter can be safely removed.
