This test is crashing on the GTK build:

http://build.webkit.org/builders/GTK%20Linux%2032-bit%20Debug/builds/10225/steps/layout-test/logs/stdio

It also happens on the chromium builds. Here's the backtrace I'm seeing on the chromium build bots (I think - I'm not 100% sure if this is up-to-date or an old stack trace):

It looks like it started happening somewhere between r67898 and r67907. I suspect r67903, but I'm not positive.
