For the existing release following workaround can be used in the meantime to resolve this issue
1) Log in to the web version of Feedly at http://cloud.feedly.com
2) On at least one article at least add one tag or mark it for "save for later" (with bookmark icon)
3) Restart gNewsReader application if it was running
After these steps you should be able to load the above mentioned special feeds just fine. The workaround is needed to be done only once.
