This is the wrong mailing list - meta-ti has nothing to do with qtbase.

Moreover, why are you still using 5.1.1? There were many fixes in Qt5 5.2.x 
and 5.3.x. Also, it depends on your setup and what layers and features you 
configure. Either way, it's a discussion for a distro layer, you can use 
meta-arago mailing list for that...
