[Dovecot] SORT with unknown charset bug?

[A.L.E.C]

I'm not sure this is a known bug. I'm using dovecot 1.1.19.

C: s SORT (DATE) blah ALL UNDELETED OR HEADER SUBJECT {4}
S: + OK
C: asdf HEADER FROM {4}
S: + OK
C: asdf
S: * SORT 1 2 4 5 3 6 7 (... all messages in folder)
S: s NO [BADCHARSET] Unknown charset

I think there shouldn't be "* SORT... " response.
