Kenny thought it would be nice, rather than pass the actual bb info to free to the freeing function, to instead pass some random bitmap.


The attached fixes *that*, but this just causes a crash deeper in trying to free some chains.

However, it looks like that is either caused by a double free, or because
 we never null out pointers to things after we free the memory for what they are pointing to.
