I had to look into the source code of gtk+ and make some tests with gdb 
to find out, and here's what I found:

The focus_in signal is emitted from the default handler of the 
grab_focus signal. That default handler selects all the text after the 
focus_in signal handler(s) have returned.

Try to connect a handler to Gtk::Widget::signal_grab_focus() and 
deselect the text and position the cursor there. Perhaps you can just 
change your focus_in handler to a grab_focus handler. Connect your 
grab_focus handler _after_ the default handler (which is the default 
behaviour of connect()).
