Is it a subclassed text-view? As I understand it, you have to implement
the GtkCellEditable interface. (Or is it a custom renderer you need? - I
can't remember).

Anyway, in the application I observed the bug in, it was fixed by
setting the "height-request" property on the text-view when it was
created to do the editing. We set this to the height of the cell, which
(give or take padding errors), appears to do the trick.

I still wounder if the text-view ought to specify a height-request which
is big enough for at least one line though?

Perhaps some properties akin to "fill", "expand", "alignment" might make
the GTK codebase more generic in its handling of cell editors?
