Check, and I think you'll find you get exactly one event
with:
 
  event->type == GDK_BUTTON_PRESS

for each event event with event->type == GDK_BUTTON_RELEASE.
You are just getting more events with type 
GDK_2BUTTON_PRESS, and GDK_3BUTTON_PRESS.

(For a double click, gdk sends:

 GDK_BUTTON_PRESS
 GDK_BUTTON_RELEASE
 GDK_BUTTON_PRESS
 GDK_2BUTTON_PRESS
 GDK_BUTTON_RELEASE)
