mail_daemon crashing notification_server

[humdinger]

This is hrev43515.

In my quest to fetch mail with the mail_daemon, I updated to the latest revision. Fetching mail with activated notifications crashes the notification_server with this backtrace:

[tcsetpgrp failed in terminal_inferior: Invalid Argument]
Thread 822 called debugger(): Trying to delete a view that belongs to a window. Call RemoveSelf first.

Calling notify "Test" from Terminal works.

Cannot reproduce anymore with hrev43630. Maybe it was some glitch in my setup... might not be "fixed" but "invalid", who knows.
