Marking as "major" since it makes the feature unusable.

Thanks for pointing this out. I have updated all the messages with the latest translatewiki translations and set it it to use the English fallback were it can't find the localized string in r74758 and deployed it.

Also the pt gadget was pointing to an old version of the gadget. I have updated the path on the gadget.

I have also renamed the gadget to match the resource checks and default rewrite rules ie there should be two pages one 'MediaWiki:MwEmbed.js' used for rewrite urls and the gadget 'MediaWiki:Gadget-mwEmbed.js' used for turning on the gadget permanently.

Now links like the following should work and give you a working 'enable this gadget button' in your local language:
http://pt.wikipedia.org/w/index.php?title=Wikipedia:Habilite_o_Add_Media_Wizard&action=edit&withJS=MediaWiki:MwEmbed.js

Thanks for your help!
It seems to be working now.

Questions:

• When I have the gadget enabled in my preferences and I click in the link

http://en.wikipedia.org/w/index.php?title=Wikipedia:Enable_the_Add_Media_Wizard&withJS=MediaWiki:MwEmbed.js
(which is in that page) the button in the top is not shown. Is this the expected behavior? Shouldn't it display some message like "You already have mwEmbed enabled"?

• If I click in "edit" and "preview" the edition of that same page, the video in the right side changes to the old interface. Shouldn't it use html5 in preview too?

Should I create new bug reports for some of these things?
