Please file a bug for this on bugs.maemo.org in the gPodder component of Maemo Extras. Yep, thanks for pointing that out. I have fixed this error (mostly as a result of changing the code to allow multi-episode playback on the Desktop version) in 0.17.0-2 which has just been uploaded to the Extras Builder, and should appear in Extras-Devel today. Please report back if this works for you as expected, and I'll promote the package to Extras after that. For the other bug (password-protected feeds?) please also don't forget to file a bug report.
