Generally I do that by popping up a dialog for anything editing of
multi-line text from a treeview.

GtkCellRendererText uses a GtkEntry and finishes the editing by way
of the ENTER key (or cancels it by way of ESC key)... you could theoretically
write your own GtkCellRendererText derived renderer that uses a
derived GtkTextView to implement GtkCellEditable... but... if you did
that I'm not sure it would be a good user experience (i.e. how would
the user indicate that they finished editing the cell ?, you would have
to put a button in there or something ?).

In the end I recommend using a dialog that pops up from the treeview
to edit multi-line text.
