This bug was five years old. It was a tiny copy and paste error that David made 
when trying to get GNUstep to compile with clang. We don't have a release note 
for this change, so you wont find it in the ChangeLog file.

Glad that this helped you. What I still don't understand is why a copy of the 
cell gets used in the first place.
