Today I took the time and uninstalled the 32-bit Carbon version of Qt, 
and then replaced it with the 64-bit Cocoa one.  All font problems went 
away just like that.  I didn't know that there's this big of a 
difference.  Since Carbon will be deprecated in the next Qt version, I 
guess this isn't worth reporting.

All I can say is that if you're using Carbon Qt, it's worth replacing it 
with the Cocoa version.  I wish someone had told me sooner :P
