I can't duplicate this behaviour.  Both

  dpkg-reconfigure -plow -freadline locales

(which prompts), and

  dpkg-reconfigure -pcritical -freadline locales

(which doesn't) work fine, and glibc doesn't choke.  Adding tracing to
the xmalloc/xfree calls in Gnu.xs produces:

  0x1069b7b8 Gnu.xs:239 xmalloc(20)
  0x106ec290 Gnu.xs:239 xmalloc(21)
  0x106ec2b0 Gnu.xs:239 xmalloc(25)
  0x106ec2e0 Gnu.xs:239 xmalloc(17)
  0x10732638 Gnu.xs:2582 xmalloc(8)
  0x1073cc40 Gnu.xs:239 xmalloc(18)
  0x1073cc58 Gnu.xs:239 xmalloc(14)
  0x1073e008 Gnu.xs:239 xmalloc(27)
  0x1073e008 Gnu.xs:1540 xfree(s)
  0x1073df18 Gnu.xs:239 xmalloc(23)
  0x1073df18 Gnu.xs:1540 xfree(s)

No double-frees there.
