"PPtr cast failed when dereferencing! Casting from Mesh to Renderer!"

or
Select the "Terrain" object in scene, go to Place Trees, select the tree and remove it

Encountered exactly the same issue (frame-debugging a Unity scene containing only a Unity Terrain object with trees placed):
Number of errors reported is directly proportional to number of active tree instances within the current view frustum at the moment the debugger's 'Enable' button is clicked.
[Unity version 5.4.2f2] - Unity console trace as follows:
PPtr cast failed when dereferencing! Casting from Mesh to Renderer!
