As Will noted, you disable fontenc with these lines.

The problem was that microtype did not correctly expand the variable 
"rm*" in the \SetTracking definition. It would have worked if you had 
written:

\SetTracking{encoding={*},family={TeX Gyre Bonum},size={8}}{188}

I've fixed this now in tlcontrib, so that you can remove lines 5 and 7 
again, and still say "rm*".
