On my machine, where you get the signal 11, mine initialises the GL
renderer, so it may be a problem with the GL libraries, or permissions
on them.  Here are the permissions on mine:

$ ls -l /usr/lib/libGL.so
lrwxrwxrwx    1 root     root           17 May 18 16:19 /usr/lib/libGL.so -> libGL.so.1.0.1251

$ ls -l /usr/lib/libGL.so.1.0.1251 
-rwxr-xr-x    1 root     root       248932 May 18 16:19 /usr/lib/libGL.so.1.0.1251

Also, do you have a symlink to the libGL in your quake3 directory?
When I ran Quake on X3.3.6, I used to have to make a symlink there,
but its not needed with the nvidia drivers.

You could also try starting Quake and specifying the libGL library on
the command line, like this:

quake3 +set r_gldriver /usr/lib/libGL.so.1.0.1251

You can also try deleting the .q3a directory in $HOME and then letting
it recreate the startup files.

Cheers,
Sean
