memprof reports memory leak with GtkCalendar

["Evan Martin" <eeyem u washington edu>]

memprof finds a memory leak when I use the GtkCalendar widget.

The attached test program demonstrates this:
It creates a window with a button, which, when clicked, pops up another
window containing a calendar.
As I understand GTK, closing this window should properly destroy the calendar.

I have also attached the memprof leak information after running the test
program with debug versions of the GTK libraries, and popping up a calendar
twice.

Is this a true leak?  Or is memprof misreporting?
