new cell is bugged when created.

[Charlescad]

Hello, When i create a new cell via ein:worksheet-insert-cell-below-km, it sometimes create a new cell in the sense that I see "In [ ]:" but it is not possible to write anything and the indow to enter text below does not appear. It does not happen everytime but randomly. Once it happened, it is very unconvenient: I cannot kill, nor save the buffer any longer! When i try to save for instance I get:

Unbound slot: ein:codecell, "#<ein:codecell ein:codecell-8ab6b31f44>", input, oref

More precisely when I try to add a new cell (ein:worksheet-insert-cell-below) I get:

ein:worksheet-insert-cell-below-km: Wrong type argument: number-or-marker-p, nil

This is what a "toggle-debug-on-error" gives me:

`Debugger entered--Lisp error: (wrong-type-argument number-or-marker-p nil) poly-ein--relative-to-input(19 #)
