Hi,
After reading a tantalizing entry in the SVN log file, I just had to 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:

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.

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?
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...
Trying to drag the right resize handle of the text box doesn't work; dragging the left handle does.
It's great to see the progress made with SVG filter support!
