 Running any of the MythTV GUI programs (mythfrontend, mythwelcome, myhtv-
 setup) on Ubuntu Mate xenial results in the follwoing log messages before
 the main window is displayed:
 {{{
 Unable to find an X11 visual which matches EGL config 20
 Could not initialize OpenGL for RasterGLSurface, reverting to
 RasterSurface.

 2016-04-28 14:13:10.555581 I  Using Full Screen Window
 Handling Segmentation fault
 Segmentation fault (core dumped)
 }}}

 The back trace on the core dump is as follows:
 {{{
 Examining core dump with gdb gives this backtrace
 Program terminated with signal SIGSEGV, Segmentation fault.
 #0  0x7127314c in platform_get_handle () from /opt/vc/lib/libEGL.so

 }}}

 These all work fine on ubuntu wily.

 I am looking into this, but I am hampered by the fact that gdb is not
 working on raspberry pi xenial: https://bugs.launchpad.net/bugs/1576432

 This will take me some time to figure out.
