[wp-hackers] tinymce and wp-admin/undefined/langs/no.js

[Per Søderlind]

Hi,

I'm porting/rewriting ImageManager (www.soderlind.no) to WordPress 2.5. It's
almost done, but I get a javascript error and Firebug tells me it's
wp-admin/undefined/langs/no.js .. anyone know where it is defined? 

Regards,
