Jay, if the minefield build is from mozilla then you can put about:crashes into the address bar, enter, and drag the links to a comment here.

Sigh...after submitting the bug report, I deleted the minefield build. So I went and re-downloaded it, and I can't make the thing crash again! (although the website does render horribly) [It still crashes on the default 3.0.0.10 build from Ubuntu.]  The version of minefield did not change between downloads
rv:1.9.2a1pre) Gecko/20090522, and I don't know what did change...

This is caused by background image http://www.wreckracing.com/themes/wreckracing/bg.png that is too large (2x60000 px). It is referenced in style.css:

body {
  color: black;
  background: #FFFFFF url(bg.png) repeat-x;
}

The crash bas been fixed in bug 424333 but rendering of the page is broken. I've created a testcase to show that. Everything is OK when the large image is used in img tag (imgsrc.html in the testcase). Rendering is broken when the image is set as background image (background.html) or when the image is specified directly in the URL bar (x_32768.png).

I'm not sure how to fix this, but if it is a problem to handle such large image in these situations then the image should be ignored instead of breaking whole page.

I have tested with 3.6.13 using the testcase provided by Michal Novotny ( attachment 381651 [details]) [as the original website has had it's image fixed already].

I saw no problems with the rendering, so I believe this bug has been quashed!
Thanks all!
