Talking to myself again...

Attached is a patch which fixes the issue, but it needs checking that it
is indeed the correct thing to do.

Previously we had that clib was allocated in the embeded component
state, and so we free'd it. Actually, it appears that clib comes from a
hash table owned by libgeda, and should NOT be free'd.

Patch attached.
