if you search the mailing list archives there was a previous discussion on this, without seeing a gdb backtrace it is hard to comment, but it looks like it could be a bug in the mesaGL library, or some non standard feature that stage is using wrong. You could also search for any known issues in mesaGL around this, and try installing a debug build of it and see if that gives any more detail.

I try to upgrade my Ubunti to 8.10 Interpid and reinstalling player
and stage, I use same scripts which work in 8.04.1. Have got the
latest player  2.1.2 and Stage 3.0.1.
I get following error:

user@ubuntu810desktop:~$ cd Stage-3.0.1-Source/
user@ubuntu810desktop:~/Stage-3.0.1-Source$ cd worlds/
user@ubuntu810desktop:~/Stage-3.0.1-Source/worlds$ gdb player

There seem to be a problem with openGL which didn't exist in Ubuntu
8.04. Installing glx-nvidia-new helps, but I don't want to use any
properitary drivers - only mesaGL.
Please help me!!
