Hello,

I try to solve the following bug in the new version LTS   (unsuccessful
in versions 12.10, 13.04, 13.10)

Problem displaying a white screen with Stellarium 0.12.4 (no view of the
sky, or stars)

- Xubuntu 14.04 LTS Trusty (3.13.0.13 kernel)
- Graphics Card Intel Corporation 82865G
- OpenGL packages libgl1-mesa-dri, libgl1-mesa-glx, libglapi version 10.1.0 in Trusty

Results with packet version 10.1.0:
"Grep Chipset / var/log/Xorg.0.log"

Important : Stellarium 0.12.4 + Trusty LTS with the same package
libgl... downgrades in version 8.0.4 (those Precise LTS) is OK !

** Affects: xorg (Ubuntu)
     Importance: Low
         Status: Incomplete
