+Oops, {app_name} crashed. We do our best to make it stable, but...
+
+A crash report was automatically generated with the following information:
+  - A verbatim copy of the crash traceback.
+  - A copy of your input history during this session.
+  - Data on your current {app_name} configuration.
+
+It was left in the file named:
+\t'{crash_report_fname}'
+If you can email this file to the developers, the information in it will help
+them in understanding and correcting the problem.
+
+You can mail it to: {contact_name} at {contact_email}
+with the subject '{app_name} Crash Report'.
+
+If you want to do it now, the following command will work (under Unix):
+mail -s '{app_name} Crash Report' {contact_email} < {crash_report_fname}
+
+In your email, please also include information about:
+- The operating system under which the crash happened: Linux, macOS, Windows,
+  other, and which exact version (for example: Ubuntu 16.04.3, macOS 10.13.2,
+  Windows 10 Pro), and whether it is 32-bit or 64-bit;
+- How {app_name} was installed: using pip or conda, from GitHub, as part of
+  a Docker container, or other, providing more detail if possible;
+- How to reproduce the crash: what exact sequence of instructions can one
+  input to get the same crash? Ideally, find a minimal yet complete sequence
+  of instructions that yields the crash.
+
+To ensure accurate tracking of this issue, please file a report about it at:
+{bug_tracker}

+If you suspect this is an IPython {version} bug, please report it at:
