Dude are you on an Rpi? Cause i can link you to a precompiled qt5.3.1 that works perfectly with reps (just missing a few ones but you can get them from jessie).
Btw spots i've compiled the qt5 wallet and that exchange tab is really nice

sudo apt-get update
sudo apt-get install libxcb-icccm4 libxcb-image0 libxcb-randr0 libxcb-render-util0 libxcb-sync0 libxcb-keysyms1
I asked a native French speaker to check it and he said it looked like Google Translate, that's why. Sorry if that's not true
Is there a bounty for an Italian thread?
