The server does not crash, it's just the error message returned that indicate this.

The same problem occurs if you call mysqlshow with an unknown database. Like:
>mysqlshow test2

Lowering priority and removing showstopper flag.

This happens because when the server detects the errror, it calls close_connection without any error code. This means the error is never sent to the client and thus it believes the server has crashed.
