Fixed for me by deleting unused material slots in a Meshrenderer.
Mesh Baker produced Meshrenderer with two material slots but only one is actually assigned to a mesh.
A better error description and a reference to the problematic renderer would be nice, I had to go through every renderer and delete materials to see if something pink appears.

I had a lot of sprites so finding the fully-transparent frames was not something I could do by hand.
So I wrote a script that goes through all of your sprites and finds sprites without opaque pixels. It might benefit you:

Same with 5.6. Lots of sprites so a pain to try a figure out where the empty sprite frame is. Also like to use empty frames in animations sometimes for timing reasons etc.

S37 I had the same issue. I opened up the sprite sheet in Gimp and found the culprit an invisible sprite ...I got the paint brush and put he smallest pixel "dot" on it...now no errors... THANKS!

After upgrading to unity 5.6 (now p1) I get this error. It was not in 5.5. Any ideas?
Dynamic batching: index buffer source is NULL (first IB byte 0 count 0 first vertex 0 offset 0)
I got it in 5.6 p1.
Disabling dynamic batching does not fix it.
I did manager to isolate it to a 256x256 png sprite with 0 alpha. So it's invisible/clear. If I turn it off then the error goes away. I do have other pngs with alpha at 20, 40, 60, 80 and 100 with no issues. So the warning is given every frame with the alpha set at 0.

In sprite animation you have transparent frame (maybe you cuted it from sptitesheet). DELETE IT!

Same as ROBG88 is saying - earlier when on 5.5.0f3 this issue wasn't present when using the JellyGarden Framework from Asset Store, but in 5.6.0f3, this has started showing up.
Even disabling Dynamic Batching from Edit>Project Settings>Player did not fit it.
