Thanks, Michal.

I really haven't thought about using g_steal_pointer in this case.
Taking a "review 101", I'd really expect this to be pointed out as:
- If I missed this, it happened most likely because either I'm not
aware of this or I didn't see the opportunity of doing such change;
- Saying something could be changed but not pointing out what makes
the life of **any** developer harder as the developer has to solve a
puzzle in order to understand the comment;

Please, for the next round, consider (and, at this point, you already
know that) that I'm not as smart as the reviewer and point out what
has to be changed. :-)

Michal went one step further and even provided the diff, it's not
needed, but I'd really expect to be pointed to what's wrong during the
review.

I'll go ahead and push the series.
