You might ask, how did mXULWindow become null.

545 void nsChromeTreeOwner::XULWindow(nsXULWindow* aXULWindow)
547    mXULWindow = aXULWindow;

http://bonsai.mozilla.org/cvsblame.cgi?file=mozilla/xpfe/appshell/src/nsXULWindow.cpp&rev=1.151&mark=458,537#526
458 NS_IMETHODIMP nsXULWindow::Destroy()
537       mChromeTreeOwner->XULWindow(nsnull);

And what was i doing to cause the window to be destroyed?

with the condemed window as my evaluation object (because i was stopped for an
exception/error in that window), i evaluated:
window.close()

and then i pressed continue.

oh right, i suppose the actual crashing bits should be mentioned :),

NS_IMETHODIMP nsChromeTreeOwner::SetEnabled(PRBool aEnable)
{
   return mXULWindow->SetEnabled(aEnable);

	aEnable	1	int
+	mXULWindow	0x00000000 {mRefCnt={mValue=??? } mChromeTreeOwner=???
mContentTreeOwner=??? ...}	nsXULWindow *

FWIW, no crash-status hits for signature contains nsChromeTreeOwner::SetEnabled in past 30 days.

Closing because no crash reported since 12 weeks.
