No, me neither - going without the temporary is much neater and I can't
honestly see why it is technically needed. However, it's done this way
elsewhere in geeqie's code and I didn't have time to sort out whether it was
required for the proper functioning of things like garbage collection, or
just a leftover remnant from earlier changes.
I'm happy to take advice on this from others who are more familiar with
geeqie's internals.
