cron error - code 127

[elzo valugi]

I get this error by email, daily, when there are no updates. When there are I get a regular email.

/etc/cron.daily/apticron:
/etc/cron.daily/apticron: 3: 52: not found
run-parts: /etc/cron.daily/apticron exited with return code 127

this is the cron line

52 1 * * * root test -x /usr/sbin/apticron && /usr/sbin/apticron --cron

Is this an error from my part?
Thanks
