NPE on Save

Hit Cmd+s on an unsaved tab, and received the NullPointerException below. Error repeats if Cmd+s is pressed again. Saving the tab with a new filename, stops the error. This has only happened once so far, but felt it was worth reporting. An internal error occurred in: java.lang.NullPointerException The error may have affected the application state. Please notify vendor.
