Wierd error when activating an Entry

["Alex Ward" <coventry67 hotmail com>]

I was getting this when using the old 0.12 lib so I moved to 0.22 but it is 
still the same.  I'm guessing I'm just doing something wrong.

   $new_query_name_entry=Gtk2::Entry->new;
   $new_query_name_entry->signal_connect(activate => sub { print 
"clicked\n"; 1});

When I add some text into the Entry and press return I see the "clicked" 
text printed but then get the error below printed too.  Any ideas?
