Hm, i compiled now the libGLU in src-glu/ from Mesa-4.0.1 source.
After linking it, installing it to /opt/Mesa-4.0.1/lib/ and linking the
Program to it, the segfault i posted didn't occur.
from ldd of programm:
libgtkgl.so.5 => /opt/lib/libgtkgl.so.5 (0x40066000)
libGL.so.1 => /usr/lib/libGL.so.1 (0x4006c000)
libGLU.so.1 => /opt/lib/libGLU.so.1 (0x400d8000)
elmex@enceladus: ~$ ll /opt/lib/libGLU.so.1
lrwxrwxrwx 1 root root 31 Feb 7 19:04 /opt/lib/libGLU.so.1 ->
/opt/Mesa-4.0.1/lib/libGLU.so.1*
(I am shure the libs pointing to the compiled one (i removed old libGLU))
Butanother one:

This segfault occurs _after_ i did, what the first segfault caused.
This occurs, when opened the 'TexturePicker' one or two times.
Here is some info, which may helps:
