Fatal error "The script tried to execute a method or access a property of an incomplete object"
I have written an extension which has a scheduled task for sending out email notifications, this worked flawlessly with version 4.4 but now I receive the following error message in the Scheduler module.
Not sure if this is a bug or if I need to amend my code for the coming v4.5
Fatal error: tx_scheduler_Module::listTasks() [<a href='http://uk.php.net/manual/en/tx-scheduler-module.listtasks.php'>tx-scheduler-module.listtasks.php</a>]: The script tried to execute a method or access a property of an incomplete object. Please ensure that the class definition "Swift_RfcComplianceException" of the object you are trying to operate on was loaded before unserialize() gets called or provide a __autoload() function to load the class definition in /usr/local/typo3/TYPO3_4-4.svn/typo3/sysext/scheduler/mod1/index.php on line 1153
