[Bug 341898] Re: Mythtv frontend does not display any fonts

OK, so some basic sleuthing led me a few data points that will be useful
in helping to debug this.

I took a use case of running mythtv-setup on a fglrx/jaunty install no
problem.  I then spun up a6 in virtualbox( using vesa ), and tried to
run that same functional mythtv-setup X forwarded on the virtualbox X
instance.  Problem occurs.  So here's what you can take from that:

1) This *does NOT* happen on fglrx or nvidia closed source modules.
2) This *does* happen on on vesa

We've at least got a use case for reproducing.  Live disks do it
reliably when using vesa.

I went a little further and started spewing printf's all over mythtv
code to figure out when the first BadMatch shows up.  Around line ~612
of mythmainwindow.cpp, there is a show() call.  As soon as this call is
executed the first BadMatch comes up.  It's not clear if the other X
errors are caused by show() calls as well.  show() is inherited from the
parent class of MythMainWindow, QWidget.  That means that this bug
actually lies somewhere in QT and it's interface to X.  This wouldn't be
too much of a surprise considering it hasn't changed at all since
Intrepid, and there quite possibly has been X changes in Jaunty.
