[TYPO3-mvc] Misleading exception "The controller name must be a valid string"

[Georg Ringer]

Hi,

there is a misleading exception if using flexforms and forgetting to
register the controller/action in ext_localconf with
Tx_Extbase_Utility_Extension::configurePlugin():

"The controller name must be a valid string, boolean given".

It would be nice to have there a better exception for that. I opened a
ticket for that so that it is not forgotten:
