This error is going from OpenGL itself. GL_FRAMEBUFFER_UNSUPPORTED is a constant reported by opengl.. are you going to introduce separate error-handling method for each and every possible error code which opengl produces (includes hundreds of extensions and more coming each year) ? If yes, then i wish you good luck! :) The complete error description can be found in corresponding OpenGL documentation. As well as recommendations what to do and what not.

Hi Nicolai, What are your system specs?, specially your graphic card. Roassal3D requires a graphic card with at least OpenGL 2.0 support.
