[mythtv] Mythfrontend core dump

I've been trying to track down a core dump in mythfrontend.  about 2 out 
of every 3 times I try to start the FE it core dumps.  I've tried all 
sorts of cures; different nvidia drivers, different settings, different 
versions of trunk, and nothing seems to help.

When it succeeds the GUI comes up and doesn't core dump there is a 
flicker - the GUI comes up, and just before the text comes up, the 
screen goes black, there is a flicker as though the resolution is 
changing, and then the text comes up.

It always dumps in libGLcore, so it's some sort of nvidia/myth issue.
