You could try removing the /home/user/.osso_rss_feed_reader directory, which should reset the configuration. If that doesn't fix the issue then you can try reinstalling the osso-rss-feed-reader and oss-rss-feed-reader-lib packages using "apt-get install --reinstall" (you'll need to be root to run that).
