I think I was closing a Window (mail or a browser) but I'm not sure.

I was closing a window. I got the assertion for the next window I closed too.

Not a DOM problem.

Comment 3

[Mark Kaplun]

I have tried to analyz what is going on, and IMHO the root cause for the
assertion is that nsXULContentBuilder::ReplaceMatch tries to remove content
which do not match the template, and therefor do not have any XUL element
associated with it. 

IMHO not finding an element for a resource is a legitimate situation and the
assertion should be removed.

Here's a quick way to reproduce:

1) Start browser
2) Open prefs dialog (Edit/Preferences in menu)
3) Close browser window
4) Cancel prefs dialog

WFM - I don't see this assertion with current FF 1.5 or Seamonkey: Mozilla/5.0 (Windows; U; Windows NT 5.1; en-US; rv:1.9a1) Gecko/20060101 SeaMonkey/1.5a

do you still see it?
