please help me with compiler errors problem,below is the error generated by unity console

Assets/GoogleVR/Scripts/Video/GvrVideoPlayerTexture.cs(595,7): error CS1622: Cannot return a value from iterators. Use the yield return statement to return a value, or yield break to end the iteration.

when i click the error i percieve the following code on mono Developer:

private IEnumerator CallPluginAtEndOfFrames() {
    if (processingRunning) {
      Debug.LogError("CallPluginAtEndOfFrames invoked while already running.");
      return **false;**

It’s obviously a bug in the script. Just change the line to “yield break;”
