Comment(by felix):

 A simpler case:

 {{{
 (import scheme chicken)
 (require-extension srfi-69 srfi-1)

 (define t (make-hash-table hash: symbol-hash))

 (hash-table-set! t 'k1 1)

 (print (hash-table-ref t 'k1))

 (define t2 (hash-table-copy t))

 (print (hash-table-ref t2 'k1))
 }}}

 The last change to this copying routine was commit 735a6304 by ckeen,
 which was signed off by me. Reverting this patch doesn't seem to make the
 problem go away.
