message_template = "Oops, {app_name} crashed. We do our best to make it stable, but...\n\nA crash report was automatically generated with the following information:\n - A verbatim copy of the crash traceback.\n - A copy of your input history during this session.\n - Data on your current {app_name} configuration.\n\nIt was left in the file named:\n\t'{crash_report_fname}'\nIf you can email this file to the developers, the information in it will help\nthem in understanding and correcting the problem.\n\nYou can mail it to: {contact_name} at {contact_email}\nwith the subject '{app_name} Crash Report'.\n\nIf you want to do it now, the following command will work (under Unix):\nmail -s '{app_name} Crash Report' {contact_email} < {crash_report_fname}\n\nTo ensure accurate tracking of this issue, please file a report about it at:\n{bug_tracker}\n"
