This is a known problem and it has been fixed in the repository:

http://hg.rename-it.nl/dovecot-1.2-sieve/rev/a890258aa5a9

This bug was actually present for quite some time. It was however 
shadowed by another bug that was fixed in the latest release, exposing 
this one.

You can apply the above change as a patch to fix the issue during the 
time that there is no new release.

Stephan.
