[Inkscape-devel] Filter Effects don't work for me

I've got revision 16207 which appears to work fine except for filter effects, which don't work at all. The dialog is all there, it just doesn't do anything when I add an effect and change a value.

The strange thing is that, when I add a gaussian blur from the fill/stroke dialog, it does appear in the filter list, and I can change the value from the filter effects dialog, and it appears to work as it should. But I still can't add a gaussian blur from the filter effects dialog directly and edit it.

This has happened with several recent builds. I've not gotten one that works yet. Am I missing a newly required lib or something?

Thanks.
