Tried to open http://dev.w3.org/SVG/profiles/1.2T/test/svgHarness/animate-elem-227-t.svg but crashes. 170529 1 ap 2009-12-10 14:27:15 -0800 SVGFontFaceUriElement::loadFont() tries to call setSVGFont on a null m_cachedFont. And m_cachedFont is null because we're trying to resolve "../images/SVGFreeSans.svg#ascii" in an about:blank document, and of course fail. It's definitely a bug loadFont() that it crashes when font URL is invalid. It may be a bug elsewhere that the document base URL is about:blank. 171492 2 44810 jschuh 2009-12-14 11:59:21 -0800 Created attachment 44810 Proposed patch Checks for NULL m_cachedFont before calling setSVGFont(). 171493 3 44811 jschuh 2009-12-14 12:00:24 -0800 Created attachment 44811 Minimized test case 171496 4 jschuh 2009-12-14 12:02:24 -0800 I ran into the same thing last week <http://crbug.com/29890>.

Yep. I had to set up a proper WebKit build environment, but I'll be submitting a patch today. 172787 7 45072 jschuh 2009-12-17 08:23:12 -0800 Created attachment 45072 Patch with layout tests and changelog This patch just checks for a NULL m_cachedFont before continuing.

So, I copied format and style from the text-font-invalid.html test, which looked similar to this case. 172927 11 45104 jschuh 2009-12-17 12:53:52 -0800 Created attachment 45104 Patch with layout tests I fixed the typo and condensed SVG and HTML into a single file.
