Sentry Crash Report:

Description Nikola Dodik 2016-10-13 17:14:15 UTC

Application: org_kde_powerdevil ()

Qt Version: 5.7.0
Frameworks Version: 5.26.0
Operating System: Linux 4.4.0-38-generic x86_64
Distribution: KDE neon User Edition 5.8

-- Information about the crash:
- What I was doing when the application crashed:

I noticed that my PC would shut down after being unplugged without going to suspend when it was critical, or without even notifying me of the battery getting low or critical. So I rebooted, charged the battery up to 21%, waited until it drained to 20% (which is what my "low" level is), and I got a small icon in the corner telling me powerdevil had crashed.

- Custom settings of the application:

The low level has been set to 20% and the critical to 15%. Now I only recently changed this, so it might very well be that this is somehow related to the crash.

-- Backtrace:
Application: org_kde_powerdevil (org_kde_powerdevil), signal: Aborted

Comment 1 Kai Uwe Broulik 2016-10-14 06:02:53 UTC

Could it be that at this point plasmashell wasn't running (or aren't you using t notification plasmoid)? Seems like KNotification used the fallback popup window which requires widgets but the new separate PowerDevil binary is only a QGuiApplication.

Comment 2 Nikola Dodik 2016-10-14 06:33:35 UTC

I think I am using the plasmoid? I honestly don't know. I'm using whatever there is in the bottom right corner of my screen. How can I find this out for you?

Git commit 11341f1a024edd907b90f34c267e107e930aebf8 by Kai Uwe Broulik.
Committed on 14/10/2016 at 07:30.
Pushed by broulik into branch 'master'.

[KNotifications] Don't use KPassivePopup without QApplication

When using KNotification from a QGuiApplication and there is no notification service present,
the application will assert.

CHANGELOG: KNotification will no longer crash when using it in a QGuiApplication and no notification service is running

Comment 4 Nikola Dodik 2016-10-14 08:00:41 UTC

Thanks for looking into it. Is there some way to pull this patch, or should I wait for the next release?

Comment 5 Kai Uwe Broulik 2016-10-14 08:22:34 UTC

You can compile knotifications framework yourself or wait for the next KDE Frameworks release in a month.
