Well, /etc/profile.d/qpa_plugin.sh sets the QPA to either "ubuntumirclient" 
(if you're using Mir (meaning you have the "$HOME/.display-mir" file)) or to 
"ubuntu" if you are not using Mir.

The "ubuntu" QPA is what we had when we used SurfaceFlinger but it seems we 
are not compiling it anymore, so my immediate guess is that you should try 
using Mir.

<some minutes pass>

Actually by looking at the qtubuntu debian/rules file it seems that it is 
still actually trying to compile it but failing to. I just opened a bug about 
that https://bugs.launchpad.net/qtubuntu/+bug/1271464

So I guess your options are:
 * Try using mir
 * If you know debian packaging try to help fixing the bug i just opened
 * If you can recompile packages, recompile the qtubuntu package with the 
dirty hack i mention on the bug
 * Otherwise wait until the bug gets fixed

Hope this helps,
  Albert
