RSS feed in Safari 8.0 is not working with enabled iCloud sync

Hi there,

I have a problem with rss feeds under Safari 8.0 and Yosemite. The standard procedure of subscribing is no problem and the feed is accessible as long as I don’t enable iCloud synchronisation for Safari. But if I do enable that feature, the feed entries are neither accessible nor is the feed itself editable in the configuration panel in the Safari sidebar. Moreover, the single feed entries seem to be bouncing in and out of the list in the sidebar.

iCloud synchronisation for Safari switched off and the problem is gone. Finally, the same feed is working simultaneously fine on my iPhone 5s and it seems barely unaffected by the behavior of Safari on the Mac.

I would be very grateful for a working solution, because Safari iCloud synchronisation is a useful feature and turning it off is not what I want.
