Summary: divide by zero crash in
RenderBox::calculateBackgroundSize with 0,0 bmp
background image
Product: WebKit
Version: 526+ (Nightly build)
Platform: All
OS/Version: Mac OS X 10.5
Status: UNCONFIRMED
Severity: Major
Priority: P3
Component: CSS
AssignedTo: webkit-unassigned at lists.webkit.org
ReportedBy: amohr at adobe.com
there's a divide by zero crash in RenderBox::calculateBackgroundSize when you
load a 0,0 bmp as the background image and specify -khtml-background-size
It crashes on:
w = bg->imageSize(this, style()->effectiveZoom()).width() * h /
bg->imageSize(this, style()->effectiveZoom()).height();
since bg->imageSize returns 0,0
