Thank you for this bug report. This bug has recently been fixed by the
following commit in the master branch of the Mesa git repo:

    mesa/fbobject: Update CubeMapFace when reusing textures

    Framebuffer attachments can be specified through FramebufferTexture*
    calls. Upon specifying a depth (or stencil) framebuffer attachment that
    internally reuses a texture, the cube map face of the new attachment
    would not be updated (defaulting to TEXTURE_CUBE_MAP_POSITIVE_X).
    Fix this issue by actually updating the CubeMapFace field.

    This bug manifested itself in BindFramebuffer calls performed on
    framebuffers whose stencil attachments internally reused a depth
    texture.  When binding a framebuffer, we walk through the framebuffer's
    attachments and update each one's corresponding gl_renderbuffer. Since
    the framebuffer's depth and stencil attachments may share a
    gl_renderbuffer and the walk visits the stencil attachment after
    the depth attachment, the uninitialized CubeMapFace forced rendering
    to TEXTURE_CUBE_MAP_POSITIVE_X.
