I had posted this fix for RSS on sourceforge some time ago. I made the fix locally.
I noticed someone did a lot of work on RSS recently, so I put the tikilib and rss.lib from 1.8 branch in my directory.
This bug still wasn't fixed, and I wanted to make sure this got on someone's radar .
In tikilib - sorry for RSSLIST.
Just below this, you will find a loop using j=1 as the initalizer.
This should be j=0;
With j=1, it always "skips" the first item in the RSS feed.
