mail01: 2.0.20
mail02: 2.1.7
mail03: 2.0.20
mail04: 2.0.20

Director for user at example.org currently points to mail02.

Compiled and installed 2.1.7 on mail02 (Ubuntu Lucid),
gettings segfaults on mail02 now.

Got a core dump and created a gdb backtrace:

mail02# doveadm -c /etc/dovecot-director/dovecot-director.conf search -u user at example.org all
