The embed function outputs garbage

Since bitbucket renewed their User Interface (around October 2012), the Embed function outputs garbage instead of usable code snippets or else.

I included the full output in a text file.
Since I can't attach more than one file,
this is the link: https://bitbucket.org/axezn/zen-axe/src/c0b5ff8165ee1939108922dcf10818c3ff4d3b6b/secondlife/scripts/compileviewer?embed=t

And this is a snapshot: https://dl.dropbox.com/u/7425443/garbage.PNG
