There is no version 2-1, you probably mean 2.1-1. You can use the Application Manager to find out which version you ahve installed. The forums are a bad place for reporting bugs. A better place is the bug tracker. Please file a new bug report at https://bugs.maemo.org/enter_bug.cgi?product=gPodder and mention that you are using the Maemo 4 (N800/N810) version of gPodder. Thank you
