This problem still exists in version MADSONIC 6.0.7960.c288541.20160122.0103
I still get the NullPointerExeption and when I click "download" on one of the already downloaded podcast files, I get this error page:
Code: Select all
HTTP ERROR 400
Problem accessing /madsonic/download.view. Reason:
Bad Request

I found the fix for this issue - you have to add your Podcasts directory as a media source, then everything works just fine. It doesn't have to be in any kind of group, it just needs to be listed as a source.

Thank You, Thank you, Thank You! Thanks for posting the solution to this. I have been working on trying to get my Podcasts working again for over year and since a 5.x build of Madsonic. I had tried all kinds of permissions related fixes on my Linux server folders etc. It does makes sense now though. When you specify a different download location for Podcasts, I guess Madsonic needs to have it listed as a media folder as you said. I guess you don't have to do this for the default Podcast download folder location since Madsonic/Subsonic will look there by default, and therefore that default path isn't listed in the media folders. I am wondering if this affects Subsonic as well as Madsonic. If it's not in Subsonic, but is in Madsonic, then there probably just needs to be a note added to the Podcast Settings page stating that you need to add the path to your Media folders (or the Podcasts directory should be shown by default in the media folders). Thanks again! I thought I was crazy!
