Hmm. Might be.  Andy noted this on #guile:

<wingo> one can reproduce easily
<wingo> scheme@(guile-user)> (make-weak-value-hash-table )
<wingo> $1 = #<weak-value-hash-table 0/31>
<wingo> scheme@(guile-user)> (hash-set! $1 "foo" "bar")
<wingo> $2 = "bar"
<wingo> scheme@(guile-user)> (hash-set! $1 "foo" "baz")
<wingo> [hang.]
