Discussion

This is a configuration problem. The rss_rc action uses config.charset as target encoding. Obviously it was set to ascii which is a very bad idea if you want to encode non ascii characters. Encoding is UTF-8 now, which solved the problem

Sure that fixes it? It is a DECODE error, this rather means that an (implicitely done) decoding of a str (which python usually does using the ascii decoder) failed. This happens if at some place it needs a unicode object, but only has a str. And as you see, there was already a fix there, using unicode(), but obviously this broke it in another way and thus was commented again.
