[mythtv] mythfrontend on ubuntu 17.04 testing X11 ICE problems

[roger]

I have set up my little Shuttle XS35V3 box as an ubuntu 17.04 testbed. I 
have built and and installed from the 2.8 fixes branch.

I keep getting this from mythfrontend on stderr

ICE default IO error handler doing an exit(), pid = 1752, errno = 32
QWaitCondition: cv destroy failure: Device or resource busy
QWaitCondition: mutex destroy failure: Device or resource busy

The old trick of deleting the ..ICEauthority file seems to work if you 
do it right after mythfrontend exits, this may be a red herring. But 
unfortunately the error will reappear at some point, most likely on the 
next boot.

This problem seems to have been around for ages.

Does anyone know what Qt is doing with ICE?

Errno 32 is broken pipe. So what is dying and why?

Seeing as I have hijacked the families myth box for testing, I am keen 
to fix this :-).

So all help will be gratefully received.
