It's usually data that's allocated once on startup and then not freed on
exit. In any case, you might have noticed that most of the stuff reported
in the attached file doesn't come from Qt, but rather from glib, gdk,
pango and other libs.

We're testing Qt on a regular basis with valgrind and try to fix the
errors and leaks that originate from Qt. Errors in dependent libs are not
really something we can do a lot about (apart from reporting them).
