In my case, this was caused by using a sprite that was 100% transparent. I added a single pixel, even at 1% transparency and it fixed it.

I'm having experiencing the same error with the Jelly Garden Match 3 store asset (https://www.assetstore.unity3d.com/en/#!/content/43260) when reskinning the standard assets with my own art.
For everyone's information - hopefully this maybe helpful to some - I installed the Unity 5.5 2D EXPERIMENTAL PREVIEW RELEASE 3 (https://forum.unity3d.com/threads/2d-experimental-preview-release-3.443661/) and did not encounter these errors after reskinning.

I have the same problem starting with 5.6 (5.5.3 was ok).
For me, the problem is caused by the Animator of game object: the animation is a sprite sheet. If I decactivate the Animator, it's ok (but then, I don't have my cartoon explosion animation)
I have several type of explosions of those on various game objects and the problem does NOT occur for every one...

Fixed it. It was an LOD mesh. Had to turn off parents until the spam stopped occurring. Then isolated the problem. Seems that LOD systems are very cumbersome in Unity.

It seems like the error lies around empty SubMeshes and its MeshRenderers. If you assign a Material in the SharedMaterials Array of any MeshRender, this error occures as long as that particular Material is used by any other SubMesh.

I'm not noticing any visual problems other than the error message. I am definitely using multiple materials/sub-meshes and procedural meshes with degenerate triangles to avoid array reallocations. Happens in latest 5.5.0f3

5.4.3p1 seems to contain a fix that could be related? "Fixed a crash when using dynamic batching". Also likely to be completely unrelated.

Am also experiencing this on 5.4.2f2 - I cant say the exact source of the issue but I am also using SimpleLOD to edit meshes so thus have procedural geometry in my scene like other people have who have reported the bug have also been using.
