[arch-general] Cantata gives error after Qt-5.3 upgrade

After updating to qt 5.3 in [testing], I found that cantata does not start up. Upon running from the terminal, I get the error: $ cantata This application failed to start because it could not find or load the Qt platform plugin "xcb". Available platform plugins are: eglfs, kms, linuxfb, minimal, minimalegl, offscreen, xcb. Reinstalling the application may fix this problem. However, reinstalling did not fix the problem. Downgrading qt to the version 5.2.1 in [extra] did. I believe that recompiling "cantata" with qt 5.3 might be required?
