TYPO3.TYPO3CR

When one of my nodes had an accessroles property set and I attempted to run (any) node migration, the following exception raised:

Uncaught exception #1358513802 in line 1116 of \Data\Temporary\Development\Cache\Code\Flow_Object_Classes\TYPO3_Flow_Security_Context.php: The security Context cannot be initialized yet. Please check if it can be initialized with $securityContext->canBeInitialized() before trying to do so.

(temporarily) removing that property (setting it to a:0:{} manually in typo3_typo3cr_domain_model_nodedata.accessroles, made the error disappear.
