I think it’s the responsibility of the sending app to guarantee valid  
HTML, similar to how we also expect it to send valid UTF-8 sequences  
etc.

Mainly for the nicer presentation. But I guess moving presentation to  
the app which produce the stack dump (or similar) is not an ideal  
design decision.
