I suggest another way. Replace the line for the HTML viewer with the 
_one_ line below and adjust @X11_WWW@ to whatever your favourite browser is:

Open=(if test -n "@X11_WWW@" && test -n "$DISPLAY"; then (@X11_WWW@ 
file://%d/%p &) 1>&2; else links %f || lynx -force_html %f || cat %f; 
fi) 2>/dev/null

This calls links || lynx || cat, and suppresses all error messages.
