This week's book giveaway is in the Mac OS forum. We're giving away four copies of a choice of "Take Control of Upgrading to Yosemite" or "Take Control of Automating Your Mac" and have Joe Kissell on-line! See this thread for details.
First: who are 'some people' and where do they say it? Links and references would be helpful for context.
Second: along the same lines, an error in isolation is usually not very informative. The only think we would be able to say from the error is that the string is invalid or perhaps there has an invalid buffer length. More information about when you see the error, when you don't, etc... might help the discussion.
