There was an issue, only producible on a junior colleague's machine, with the calculators (invalid XML data in the BMF parser). I assumed the junior colleague had broken them and my language suggested as much in conversation. They, being junior, also assumed it was their fault.
In fact I had caused it, via the installation of a DebugBar.
No matter how confident you are that someone else caused a bug, hold your tongue. It may well have been you and you'll feel embarrassed afterwards.
