I had a report on IRC that on Tb13b2 with an existing profile the "Tools -> Chat Status" and "Go -> Chat" menu items weren't hidden. There was this error in the error console: Error: document.getElementById(aId) is null Line 683 File: chat-messenger-overlay.js http://mxr.mozilla.org/comm-beta/source/mail/components/im/content/chat-messenger-overlay.js#683 The same problem didn't happen with a fresh profile. I suspect for some reason the Chat button wasn't present in the toolbar. A trivial fix seems to just add a null check before attempting to hide an element.

I'm the one that hit this. If I can do anything to assist debugging, just let me know -- I can even package up my profile if that's helpful.
Created attachment 626774 [details] [diff] [review] Fix Trivial fix (just adding a null check). [Approval Request Comment] This bug is currently quite visible on beta where the Chat feature is pref'ed off, so we need this fix on aurora and beta. Steps to reproduce on current trunk: - with Chat enabled (the default on trunk), customize the main toolbar and remove the "Chat" button. - disable chat (set mail.chat.enabled to false) - restart - notice the "document.getElementById(aId) is null" error in the error console, and the "Go -> Chat" and "Tools -> Chat status" aren't hidden.
