Ah, that's just a bug in the Vala bindings for GStreamer, then. GstObject
uses floating references, like GInitiallyUnowned. However, Vala doesn't
know that yet. The `photo_sink- field should suffice to keep the
reference, so when this bug is fixed, you don't have to do anything
special to avoid the crash. Please add the bug to bugzilla.
