Google homepage titles missing

[filpee]

I have 8 RSS feeds and a weather widget on my google homepage and recently the titles of some of those feeds have gone missing. I now have 3 feeds with missing titles. One of those feeds is actually maintained by myself and viewing the source doesnt reveal any problems that I can see.
