possible memleak with pangoft2?

[John Cupitt <jcupitt gmail com>]

Hi all, 

I'm having problems plugging a memleak in a program using pangoft2.
This program seems to leak about 250kbytes per loop on my system. Am I
doing something stupid, or should I add to bugzilla?

This is pango-1.8.1, freetype 2.1.4
