[TYPO3-ect] bug in Powermail extension version 2.0.2

[Franz]

I believe I've discovered a bug in the latest Powermail extension, 
Powermail version 2.0.2

Installed on TYPO3 4.7.4

If I ad *Powermail_frontend template into my templates*, it breaks 
extension *Image Cycle (imagecycle) Version: 2.6.5 Juergen Furrer *

As soon as I add Powermail_frontend into my templates, *Imagecycle stops 
working*

If I take Powermail_frontend out of the template, *Imagecycle* works 
again. (Not only Imagecycle is affected, other similar extension as well)

I found no section relating to extension Powermail in lists.typo3.org, 
so I wrote you you here. Hope that's ok.
