Invalid model/method definition, expecting "model/class::method", got "" instead.'

[Shemoz]

I have a Problem with Aoe Scheduler and a other Module (DHL Versenden). All other extensions works well, just this one makes a error with this message. Im using Magento Version 1.8.1.0 and Aoe Scheduler 1.5.1. Maybe someone has a tip for me.

---EXCEPTION---

It is a known issue.
Seems to be a conflict between Aoe Scheduler and modules that are using specific functions in their cron jobs.

Happens with MailChimp and Xtento's modules aswell:

• Mailchimp: Error "Invalid model/method definition, expecting "model/class::method", got "" instead" when using Aoe_Scheduler and Xtento_OrderExport mailchimp/mc-magento#501 (comment)
