[Launchpad Bug Tracker <719289@xxxxxxxxxxxxxxxxxx>]

You have been subscribed to a public bug:

The web client should never leave the user on a state where the user
cannot logout or fix the problem.

For example if security settings are misconfigured with audit_trail, the user can get an "unrecoverable error" with a traceback after logging in as non-admin, and then cannot find a way to logout to be able to fix it as admin.
If possible, these "unrecoverable errors" should be handled more like the recoverable ones that bring you back to the previous page (see the 2 attached screenshots for comparison), but in this case it should perhaps log you out or offer the option to do it.

Any other solution can be considered, as long as the user can easily
find a way to logout and get a chance to fix it as admin.

Here is an example of typical traceback for unrecoverable error:

Unrecoverable error in the server.
