Yes, it will still be in the console. The base issue here is that this is not a single bug, there are a few of those reference counting fixes in every kernel release, and probably a new bug introduced too. Currently, there seems no consensus for a doable way about how to eliminate this class of problem completely, I'm afraid.

please upgrade to the latest version and reboot - we added a small patch which at least silences the log about the issue (AFAICT it never was a critical error in the sense that anything broke) - since the logging occured roughly every 2 versions and then stopped occuring again...:

I hope this helps
For now the issue is resolved after a reboot, hopefully it is fixed for good.
