Same here, but it fails at 69% for me using the last 3 nightlies (32778, 32777, 32698). Also, I don't see a segfault message, just the Pango-CRITICAL warnings. Rebuilding webkitgtk with the freetype backend lets Acid3 finish at 100%. The tradeoff is that font rendering doesn't look as nice. Confirmed again here, same result as Josh (though I get bug-buddy popping up). Build 33029.

I'm not sure if it's the proper fix, but WebCore/platform/graphics/SimpleFontData.cpp line 70 and 85 comment out //determinePitch(); I get another segfault after this, but not sure if it's related. when I have a patch for this issue I'll attach it. *** Bug 20109 has been marked as a duplicate of this bug. *** Still valid with nightly 36309. Same error. I think the crash with pango on Acid3 is related to https://bugs.webkit.org/show_bug.cgi?id=18552. As long as pango have no support for downloadable fonts Acid3 won't pass. But the crash should be avoidable. Confirmed still present in nightly version 37698. What about comment #7? Can webkit at least not crash when fonts can't be downloaded? Right now webkit gets to 69% in Acid3 before crashing & killing Midori. So close... Also, Acid3 isn't the only place where this kind of pango crash occurs, so can the bug's severity be escalated a notch to Major? Created attachment 26232 [details]
Proposed patch
(In reply to comment #8) > Also, Acid3 isn't the only place where this kind of pango crash occurs, so can > the bug's severity be escalated a notch to Major? This would mean "Major" has any meaning... Would you create a patch if the severity is major?
