checking for bug before filing report

[Paul Davis <paul linuxaudiosystems com>]

has anybody successfully used Gtk::CellRendererText::signal_edited() ?

i just tried to hook up a handler to it, only to find that it was never
called. i reverted to connecting to the C/GObject level signal, and that
worked just fine. i did an eyeball of the code, and could see nothing
obviously wrong.

this is with gtkmm 2.6.1 (i believe).
