I just pushed the final set of commits to this branch on
http://epilitimus.com/git_repos/geda-gaf.git

After my initial commit (the one you have already seen) there is a
second batch I had done before I had your fixes to my first batch. Then
your fixes, a formatting fix, a third set of memory leak fixes and a set
of build time warning fixes. One of the fixes in the third set is the
above re-fix using  g_object_set_data_full, you can re-un-fix it if it
still doesn't pass muster. I have compiled all of these but have not
executed them, so look them over carefully. And yes there may well be
formatting errors, though I did fix those (I think) from the second batch.

There are also still a bunch of leaks, all in the gui code. I was having
a tough time figuring these out so I finally gave up. I can see where
the allocation happens but not where the free needs to go. It is
possible they are the result of library errors to the extent that parent
objects are supposed to be freeing children, etc. I can send you the
valgrind output if you are feeling really motivated. To the extent the
object lives until program termination the leaks are moot.

I'm almost cross-eyed so that's it for me for today.
