If you open the accounts page in the settings app and close it you can't reopen it

Status changed to 'Confirmed' because the bug affects multiple users.

I assume Dave meant close in the running apps in the dash. I can reproduce it that way by just closing the online accounts "app" that is shown and returning to settings.

This is not a new regression. The basic problem seems to be that online accounts is a separate app and not a plugin to system settings. Therefore we can get into some weird behavior.

The solution for this issue will come from bug #1230091

I tried this on image 237, and it seems to be working.

I get a black screen for a few seconds after hitting 'back' on the accounts page, but after closing settings, I can re-open accounts with no difficulty.

Nevermind. I just found the correct way to trigger this bug: Open settings, open accounts, swipe from left to get running apps list, close both settings and accounts with a hold-then-X. After that, accounts won't open again.

Rosa Stop assigning yourself to bugs you are not working on

Just understood this issue - when you X an app not launched via upstart, the shell won't kill it, so the service won't launch it again.

Please don't kill unconfined processes (or anyway those not started by upstart); just make sure that the window gets closed: the application will receive the "window closed" events and will take the appropriate action, which most of the times is quitting.
In the Online Accounts case, the service won't quit immediately, but after a short timeout (unless other requests are active).

Right, yeah, we should do that to upstart-started apps, too, probably - just let them shut down cleanly, only then ask upstart to shut it down forcfully. Could use support for that (term timeout) in upstart...
