I don't have this error message, but I use flightgear 3.0.0, not 2.10,

you must use flightgear 3.0.0 because a lot of bugs in flightgear have been
fixed between the 2.10 version and 3.0.0 version,

an alternative is to run the apitrace I have provided in attachment ( just
install the apitrace program, and run "apitrace replay fgfs.trace" ), tell me
if you see a green C172p ( I use the "c172p" plane, not the "c172p-canvas"
version )

my graphic card is an ati radeon HD4650 pcie ( RV730 chipset )

OpenGL renderer string: Gallium 0.4 on AMD RV730
OpenGL core profile version string: 3.3 (Core Profile) Mesa 10.2.4
OpenGL core profile shading language version string: 3.30

if you don't see a green C172p in the apitrace then the bug may occur only with
some mesa driver ( r600 for example )
