[TYPO3-english] powermail 1.5.0 backend problem

[klemens.zleptnig at boc-eu.com]

Hi,
I updated to powermail 1.5.0 on TYPO3 4.2.10. Now in the backend I always 
get the message "No powermails on current page!" but there is no date/time 
selector!? It means that I cannot use the powermail backend to list mails. 
With the previous powermail version it worked fine... any ideas what could 
be the problem?
