"PPtr cast failed when dereferencing! Casting from Mesh to Renderer!"
5. Select the "Terrain" object in scene, go to settings and turn off Draw under Tree & Details Objects
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!
