Glib uses a new memory allocate (slice allocator), you don't have to change
your  program for it. But as a consequence of this change, crashes as a result
of allocation bugs are triggered a lot easier. Some bugs we've have seen is
using g_free instead of g_object_unref and referencing a Glist  data pointer
after the element has been removed.
