Bug Description
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:

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