Beagle cron job exits with return code 1

Binary package hint: beagle

After a recent upgrade to edgy, I get an email every morning from Anacron saying:
run-parts: /etc/cron.daily/beagle-crawl-system exited with return code 1.

The positive return code is the result of he first "test" in the cron file, namely:
OPTIONS="`test -n "$CRAWL_DISABLE_FILTERING" -a "$CRAWL_DISABLE_FILTERING" = "yes" && \
                     echo --disable-filtering`"

The result of this test is 1 for the first crawl_file (crawl-applications) and the shell returns with this return code. When commenting out the set -e at the beginning of the cron file everything seems to work as it should.
