Looking at the code, I have found a possible source of this problem.

palette_invoker is a CellRendererInvoker. This invoker have a method motion_notify_event_cb attached to the treeview,
then when the mouse is moved outside of the cell, the palette can be hide.
In that case, set the path to None.
Then if you move the mouse, and after that, do a long touch over a cell,
the path is None and trigger this issue.

Keep updated CellRendererInvoker self.path updated - Fixes #4717

Since CellRendererInvoker can set the path at None if a mouse event
is out of the area of the renderer, can break the use of touch,
if happen after the mouse movement. This patch set the path,
in the point_in_cell_renderer test, for the positive case,
solving the issue.
