uninitialized variable in qgl.cpp

running the "affine" demo on Fedora 17 64-bit in VMware Workstation 8.0.4

Graphics: "Gallium 0.4 on llvmpipe (LLVM 0x300)"

qgl.cpp line 5540:
GLboolean srgbCapableFramebuffers;
glGetBooleanv(FRAMEBUFFER_SRGB_CAPABLE_EXT, &srgbCapableFramebuffers);
if (srgbCapableFramebuffers)
glExtensions |= SRGBFrameBuffer;

the variable "srgbCapableFramebuffers" is not set, thus valgrind complains about uninitialized memory. The variable should be initialized to a default value in case it is not set by glGetBooleanv().
