the widget might generate a <texarea></textarea>
as the content is empty, genshi will output this in XHTML as <texarea/> and most browser will render the html source *inside* the text area.
http://trac.turbogears.org/ticket/2287
if you want to force genshi to output html, in your development.ini :
[DEFAULT] debug = true # Uncomment and replace with the address which should receive any error reports #email_to = you@yourdomain.com smtp_server = localhost error_email_from = paste@localhost templating.genshi.method = HTML
