Found a suitable crash case thanks to the people of [irc://irc.mozilla.org#qa #qa] (in particular, asqueella and Aleksej). For full details on the bug, see [https://bugzilla.mozilla.org/show_bug.cgi?id=354300 Bug #354300].
 
Put the following code into a XUL file for a fantastic time:
<?xml version="1.0"?>
<?xml-stylesheet href="chrome://global/skin" type="text/css"?>
<window

title="Testcase #2 for bug 354300 - Crash [@ nsPopupSetFrame::Destroy] when removing popup on popupshowing">

document.addEventListener("popupshowing", doe, true);
function doe(e) {

I read through your documentation here, and it is looking good. I also spoke to Shaver by phone this morning, and we chatted briefly about this project. He suggests that you start your work by looking for a suitable '''Crash Case''', one that happens reliably. Then you need at what would be necessary in order to bisect the change set (e.g., [http://www.mozilla.org/bonsai.html bonsai] data) in order to get closer to the change that introduced the bug. Shaver suggested that robc (Rob Campbell) might be a good person to help you brainstorm on this.
