System Information
OS: Linux Mint 64bit XFCE
GPU: NVIDIA GT 640

Blender Version
Broken: 2.72.2 hash: 789eaa0
Worked: 2.72b hash: 9e963ae

Short description of error
Point lights only render one point light at a time.

Exact steps for others to reproduce the error
open .blend file
make sure that it is set to GPU rendering
enter rendered viewport shading
hide the selected lamp (the other lamp should be illuminating the sphere now)
unhide the lamp (the shading should stay the same

Can not redo with latest buildbot builds with neither gtx560 nor 760. The questions are:

Can you reproduce the issue with latest builds from builder.blender.org?
Does it only happen GPU?
Does toggling (switching to solid shading and going back to rendered viewport) render viewport helps?

It is only GPU, I would start at CPU and it would work, then I would switch to GPU and only one of the lamps would work, Later I also realised that the same thing was happening for all lamps.

I didn't try it with a buildbot. I'll test again with both latest master and buildbot.

The issue reported can't be reproduced so far, and has been moved to the BF Blender: Unconfirmed project.
If 2 other people aren't able to redo the bug after 2 weeks, it will be closed.

We appreciate the effort that goes into making bug reports, but to be able to fix bugs we have to be able to redo them.
If there is anything you can provide to help others to reproduce the problem, be sure to include it.

I wasn't able to reproduce it with buildbot hash: 435eaa7.

I probably had a problem with building. I'll try to test a bit more next time so I don't waste all your time.
