Hi,
After reading a tantalizing entry in the SVN log file, I just hadto give the latest version a try at loading SVG drawings that use filters.

Fixed a crash in modifying filter parameters in XML editor. Fixed filters not appearing, when a file with filters is loaded.
The Gaussian Blur example from my book loaded quite nicely:http://tavmjong.free.fr/INKSCAPE/MANUAL/images/XMLEDIT/GaussianBlur.svg
There are some display issues when the zoom level is greater than 100% (horizontal discontinuities appear) but overall a very nice development. I tried varying the blur radius with the XML editor but the drawing was not updated.
The Drop Shadow example loaded but did not display correctly.http://tavmjong.free.fr/INKSCAPE/MANUAL/images/XMLEDIT/DropShadow.svg
I got a number of error messages:
(inkscape:718): GLib-GObject-WARNING **: invalid cast from `SPFeOffset' to `SPGaussianBlur'
(inkscape:718): GLib-GObject-WARNING **: invalid cast from `SPFeOffset' to `SPGaussianBlur'
(inkscape:718): GLib-GObject-WARNING **: invalid cast from `SPFeMerge' to `SPGaussianBlur'
This begs the question, what is the status of filter support?
Filter support is still under development and is unstable at the moment. Play with filters at your own risk:) Truth is there are a couple of bugs still waiting to be fixed. Stay tuned on the repository logs for updates on this...
A couple of other notes. When reloading the Gaussian Blur file with
a modified blur radius, Inkscape crashed with the error message:
** ERROR **: file sp-object.cpp: line 861 (void SPObject::releaseReferences()): assertion failed: (this->hrefcount == 0) aborting...
It seems the SPFilter wasn't releasing its references properly. I have fixed this and will commit as soon as I fix some other related problems.
Trying to drag the right resize handle of the text box doesn't work;
dragging the left handle does.
Beats me...
It's great to see the progress made with SVG filter support!

Yes, I'd expect filter support to be more reliable by now, but things got slowed down. There was some great progress made though.
