FWIW this bug only happens to me when unlocking the screen saver, usually though not always after a resume from suspend. I think it happens when I start typing a password quickly and right away. (The crash does not happen immediately—a few seconds later.)
If I take care to wait a moment until the caret in the password text field is blinking steadily I seem to be able to avoid it. This hypothesis would explain why the crash seems to happen most often when the computer is under load (either from a resume, or because there is a substantial background process like a big compile)—in such cases the screen saver GUI is a little slower to react.
Alternatively it is possible the crash is related to my fingers accidentally brushing the touchpad while typing the password.
