Hi; the latest Coverity run finds a couple of issues in this code:

object_get_canonical_path() returns a string that the caller
takes ownership of, so you have to g_free() it when you've
finished with it. (CID 1391294)

Similarly here. (CID 1391293)

Could you write a patch that adds the missing g_free()s, please?
