There is an updated version in extras-testing now. I needed to change edit my device on my.gpodder.org (change name, device typ and ID) to match it with the N900.

But I am missing a button to really sync the device. When i click "add new podcast" -> " "download from my.gpodder" all I get is the settings dialog and there is no button for synching. just "overwrite server list with device list".

(sorry for maybe wrong translation because my gpodder is in german)
