-- Information about the crash:
It doesn't matter if I enter the correct password, incorrect password, or close the password dialog --- it crashes with the same backtrace every time.  100% reproducible; I'm happy to offer an account with debugger access to anyone who wants to investigate.

The crash can be reproduced every time.
