GtkEntry by default requires a fixed minimum size.

To change that minimum size you need to set the "width-chars"
property:
http://developer.gnome.org/gtk3/stable/GtkEntry.html#GtkEntry--width-chars

Notably this default behavior is not correctly documented, however
looking at gtkentry.c:gtk_entry_get_preferred_width() reveals
that there is a fallback minimum width used.
