So, someone reported this issue and you _think_ you know what went wrong. But, you can't reproduce the issue so it sounds like you're not confident if this is the right fix or if you are fixing the right problem in the first place. We can certainly apply obvious fixes, but it would be *really* nice if you could try a bit harder to reproduce this.
