Would anyone now what is causing this ? Does it occur because I'm not calling an aglSetCurrentContext() from my 2nd thread (which leads to other problems such as dynamic vertex buffers not being drawn...) ?

One OpenGL context can only be current in one thread at any given time. You have to make another (or none) context current in the 1st thread before you make it current in the 2nd. In general I suggest using one, potentially shared, context per thread. See also: <http://www.equalizergraphics.com/documentation/parallelOpenGLFAQ.html>.
