System Information
OSX 10.11.3
Intel HD Graphics 3000 512 MB

Blender Version
Broken: 2.77
Worked: 2.76b

Short description of error
Rendering with Freestyle enabled and Edge types set to Edge Mark produces error in console when object contains disconnected Freestyle edges.

Exact steps for others to reproduce the error
Attached scene contains two scenes both with a single plane. The plane in the "disconnected" scene has two freestyle marked edges and they are disconnected. Rendering this scene produces the following error in the console:

ID user decrement error: MAstroke_material (from '[Main]'): 0 <= 0

The error does not appear in the "connected" scene where an additional edge is marked as a freestyle edge. However, if Chaining is disabled in the Freestyle Line Style panel, the same error occurs.

Despite the error, edges seem to be rendered correctly in these two scenes. However, in a more complex scene I'm missing some of the freestyle marked edges in the render. I cannot be sure this is related to this bug, though.

Can confirm the issue… Note that this is more a warning that a real error - yet it should not happen (changes were made recently in how ID usercount is managed, we are now much stricter on this aspect, but it means some areas still need fixing…).

I just wanted to add the comment that I have been encountering this notification error too.
It occurs in image and animation render. In may occur during baking.
However, during command line animation render, it occurs far too much,
and takes away computation time between finishing one frame and starting the next.
