    <thetext>A couple of times, when closing a WebKit2 window, I&apos;ve seen a crash in WebPage::close. The crash happens here: &lt;http://trac.webkit.org/browser/trunk/Source/WebKit2/WebProcess/WebPage/WebPage.cpp?rev=77274#L391&gt;. This is just after WebProcess::removeWebPage is called, so my guess is that that function is releasing the last reference to this object.

I don&apos;t have a way to reproduce this, nor do I have a backtrace. I&apos;ll get a backtrace the next time this crash occurs, and try to find repro steps.</thetext>
