[Dovecot] Dovecot Sieve Broken with 1.1 RPMs?

We have been using dovecot v1:1.0.15-1_72 and dovecot-sieve v1.0.3-7 very successfully for many months but I've been unable to get dovecot-sieve to work with the latest 1.1 release. The new release seems to completely ignore our global sieve script no matter what we do.

Is anyone else using the atrpms-stable rpms packages and able to get dovecot-sieve to work correctly?

Any help would be greatly appreciated.
