SE Notifier is crashing on me now. It was working fine this morning, but when I came back from lunch the menu icon was missing. I tried restarting it, the login window popped up, it filled itself in as usual and disappeared, and then the app crashed. Here's the beginning of the crash report file (it's too long to post everything):
