Looks good, just have a few suggestions.

This seems wrong. Either name and label are leaking or you are using them after they are freed.

Please split this out into a helper.

They are indeed leaking :-P

I think it's more appropriate to use char and bare free here since these types aren't allocated by GLib.

Please declare i just above the for for loop instead of at the top.

Yes, they are, see WKStringGetCString() it uses g_malloc()
