[mythtv-users] Upgrade from qt 5.4.2 to 5.5.1

I am on wily and trying to test mythtv 0.28. It seems the below error is
caused by a qt 5.4.2 bug. I tried downloading the qt 5.5.1 binary
installer from qt.io, but that installs into /opt/Qt5.5.1. I pointed
LD_LIBRARY_PATH at /opt/Qt5.5.1/5.5/gcc_64/lib where the libraries are,
and ran the backend. The backend fails with "error while loading shared
libraries: libgstapp-0.10.so.0: cannot open".

There is a file /usr/lib/x86_64-linux-gnu/libgstapp-1.0.so.0 - so maybe
the newer version of qt needs an older version of gstreamer? But why is
it not just using the generic libgstapp.so which points to the file that
does exist?

Do I need to recompile with the qt5.5.1? If so how?

What is the best approach?

Peter

Comment (by Gary Buhrmaster <gary.buhrmaster@…>):

 Looks to be the same as #12558 which was closed as an upstream Qt bug.
 And you are on the same version as the known bad one.  Upgrade, or
 downgrade, your version of Qt.
