no g_error_free()

[hfiguiere]

There is no g_error_free() equivalent for gexiv2::GError. Therefor there is no way to fix memory leaks in rexiv2 where the GError is never freed.

note that if gexiv2::GError was just an alias of glib::GError (they are the same, aren't they?) when we could just reexport. That would require to depend on glib_sys explicitely.

What are some arguments against ripping off the bandage for relying on glib_sys? To me, it seems that relying on gexiv2 inherently means that we should rely on glib_sys explicitly... but I could see an argument against it.
