Attached file testcase (obsolete) — 
The menuitem content in this XUL template is created twice.
Attached patch fix — — Splinter Review 
The problem occurs because a call to nsXULElement::GetChildCount occurs while processing the template query which in turn calls nsXULElement::EnsureContentsGenerated which ends up trying to build the template again, causing two sets of content to be output.

This patch clears the lazy state before parsing the query.

The testcases seems to work here; I get a menu which has three different items.
Do I need to run it locally or as chrome?

Bah, looks like you need to save the test locally, or run from chrome.

fix

I was wondering whether GetChildCount would return wrong value with this change, but as far as I see no. The query part isn't generated.

Actually, this doesn't need to be blocking.
