I also experience similar problem with gliv:

Anyone have an idea of what's going on?
Comment 2 Michel Dänzer 2005-08-02 01:34:12 UTC 
I used to get a similar crash with gliv, but it was fixed in Mesa CVS a while
ago. Have you guys tried a recent CVS snapshot?
Comment 3 Roland Scheidegger 2005-08-25 08:57:56 UTC 
Just tried glest on my rv250, seems to work fine with current Mesa cvs. Not sure
how the OP got it to run though, it will bail out if GL_ARB_texture_env_crossbar
is not supported, which so far isn't in cvs yet... maybe older versions didn't
require it (1.1.0 tested).
