[mythtv] EPG crashes mfe - svn 9409

[zoiks2004-ivtv at yahoo.com]

Since upgrading from 0.18.1 to 0.19 (svn 9409) I can
no longer open the EPG from live TV without crashing
the frontend.  When I select the on-screen EPG, video
freezes permanently and I get the following errors in
mythfrontend.log:

The last lines seem to repeat indefinitely.  Then, I
reboot.

I found no correlated errors in mythbackend.log,
Xorg.0.log, or /var/log/messages.

I'm using a GeForce4 MX440 s-video output, using
nvidia's 7667 version driver.  Myth is compiled with
OpenGL vsync support, and I'm using bob + opengl vsync
deinterlacing.
