libGL/QOpenGLShader errors when starting QtQuick application

[JamesNZ]

Hi there,
I'm trying to run a QtQuick application (ButtleOFX) on my system, but I get this error when starting it:


$ ./run_buttleofx.sh

QOpenGLShaderProgram: could not create shader program
QOpenGLShader: could not create shader

Googling seemed to imply that it's because my graphics drivers don't support OpenGL 2, but glxinfo says that it supports OpenGL 3. Anyone know why this is happening?
I'm using nouveau on Fedora 21.
