Syncing Liferea against the TinyTinyRSS news aggregator broke with the release of version 0.6 of TinyTinyRSS because of API cleanups. Thanks to a patch from Sebastian Noel it is now possible to sync to all version from TinyTinyRSS 1.5.3 to most recent 1.6.2. The fix was released with Liferea 1.8.12. Please upgrade!
