I've no evidence that it does NOT happen in practice.

I know for sure that a "quick locale switcher" add-on
of my UA managed to add some weird chrome://whatever
string to Accept-Language until I fixed it manually.

<about:config> claims that my current Accept-Charset
might be iso-8859-1,*,utf-8 (sic!).

And <http://delorie.com:81/> tells me that it is in
fact Accept-Charset: windows-1252,utf-8;q=0.7,*;q=0.7

So yes, this obviously happens, PEBKAC or otherwise.

I also don't see why my UA should ever wish to send
garbage, nevertheless it does.  And RFC 2616 doesn't
even say that this is garbage, so arguably it is not.
