The core of the problem is that jit-lock relies on text-properties,
i.e. data shared between the indirect buffers, but is run "per buffer".
This can be seen also when you use two indirect buffers in different
major modes, where the font-lock behavior can be erratic, mixing the
rules of the different major modes.

I installed a patch which prevents activation of jit-lock in indirect
buffers.  In practice this means that nlinum-mode should now work
correctly in the base buffer but will not work at all in the
indirect buffer.
IOW, problem is still present but it fails more cleanly ;-)
