What OpenGL hardware and drivers are you using? It's complaining about a missing visual shortly before it segfaults in the OpenGL driver.

this is with a Intel Mobile 915GM on an Asus eee 900 i'm using xf86-video-intel-2.1.1 on gentoo

what more information can i provide?

i also see something similar on another notebook which has an ATI graphics chip. i also get a message about missing visuals and have searched for meaning around that. from what i can see, it is not causing problems, but i'm not sure.

Simon, does this still happen in trunk? I think the Visual may be a red herring and this is just a variation on the problem in #6036 which I applied a stop gap fix to yesterday.

cannot test right now as i am several thousand miles from my system. will do so on my return in 10 days time.

well i am back from my travels - took a bit longer than i expected.

anyway. i've done a lot of testing and these are my observations (all done with 19988):

if i leave the default (for gentoo) xorg-server installed then mythfrontend still crashes. if i use fglrx then i get a whole load of screen corruption (not myth's fault).

so i tricked around and installed a later xorg server and the problem goes away.

so mythfrontend will now hit a bug in xorg-server that it did not do previously

so i would say that it is fixed.
