[mythtv] Mythlcdserver crashes often

HI!

For a long time, (probably after upgrading from a 20x2 LCD to a 20x4
LCD), mythlcdserver crashes very often for me. And when it does, it will
display only menu navigation and backend recordings from there on and no
more info for watching a recording. This happens on 2 different
machines. One with a real display and one with ncurses simulation.

Using lcdproc 0.5.2

Because I had an outdated MythTV version (0.23.1) since now, I did not
report this.

But now I have 0.26-20130121 and I still see the same crashes. In the
past, it just died and now I get some crash information. Maybe this helps:
