It seems that some of my posts are appearing on Planet Debian multiple times, and others not at all. I think the problem is a strange combination between subtle bugs in Planet and Serendipity. The SF bug report for Serendipity is here. I think the workaround should fix this.
Either that, or Planet is somehow taking offense as the <slash:comments> tag that Serendipity is putting in there.
Sorry about that — hopefully it is fixed now.
What exactly was your work-around, and does it really work?
I am banned from the planet because of this bug, and I’d like to come back…
I went into the plugin settings for the “Syndicate This Blog” plugin and set the “Field ‘pubDate'” option to YES.
There is a bug out there someplace where YES here actually means NO. So at some point when this bug gets fixed, you’ll want to flip this back to NO.
This seems to have fixed it so far.
OK, that wasn’t quite right… see the latest story on this.
