Yes, I've seen this too. Not sure what to do. We could disable "AMS always" 
for XeTeX, if necessary, but I guess we need to do some more research yet.

The reason for this is that XeTeX now uses polyglossia, which does not know 
these \addto commands (which are from babel). Are these templates shipped 
with LyX? If so, we need to embrace these calls in
