No, some messages are harmless. Only bugs must be reported. If you have an application that has a bug and present this message, please open a new bug report.
When your console is spammed by repeating error it's not a good program behavior, and should be fixed. You can view it as usability bug. Or, at the very least, it could be considered a "feature request". Feature requests are also handled via the bug tracker, so an issue is not invalid just because it's not obviously a bug.
