Hmmm, I run Worksation on Mesa drivers all the time and haven't seen this.

Are you using Mesa from git/master or the 7.8 release or ...?

One thing you could do is log all the shaders to files to try to find 
the shader causing trouble.  Do "export MESA_GLSL=log" then run 
Workstation.  You should wind up with a bunch of shader log files with 
names of the form shader_N.vert and shader_N.frag  The last one will 
probably be the one of interest.
