Set Tags with Batch process throws error

[webgras]

Hi,
I am using podcastmanager with J3.6.2 - works great! :)

But when I try to set tags for multiple podcasts with the Joomla batch button (from list view) I get the following error:
0 Call to a member function setNewTags() on null
And for all checked podcasts the feed is cleared and manually setted tags are gone, too.
