problems with glCopyPixels and multisampling

Are there any known problems, or common gotchas, with doing a
glCopyPixels operation on a window with a multisample buffer? In my
application I disable everything I can think of (multisampling,
blending, depth test, etc.), set the read buffer, load up the color
matrix to do rgb to bw conversion, and then call glCopyPixels. On an
O2 this works as expected, as does it on an RE2 with a
non-multisampling visual. With multisampling, however, the result is
washed-out bands of black and white composited with the original
image. What's up with that? What am I doing wrong?
