Sentry Crash Report:

Description Sylvain 2016-11-13 22:02:20 UTC 
Application: plasmashell (5.8.2)

Qt Version: 5.7.0
Frameworks Version: 5.27.0
Operating System: Linux 4.8.4-1-ARCH x86_64
Distribution (Platform): Archlinux Packages

-- Information about the crash:
- What I was doing when the application crashed:
I just clicked on the 'eject' button in the notification area to eject the optical disk from the reader device. Then, I was prompt for the root password, I entered it and clicked on OK. While removing the ejected disk, the desktop crashed.

- Unusual behavior I noticed:
After crashing, the desktop reloaded itself and an icon notifying that a crash occured appeared in the notification area. I also noticed that the wallpaper of my second monitor was rested to KDE's default (but not the wallpaper of the primary screen) and when I open back my browser (chromium), all my tabs were closed and I wasn't prompted to retore my previous session after a crash (witch was the expected behavior). I know that Chromium has nothing to do with KDE but maybe the behavior is symptomatic of something ...

-- Backtrace:
Application: Plasma (plasmashell), signal: Segmentation fault

Comment 1 Marco Martin 2016-11-16 12:25:43 UTC 
seems the same bug as
https://bugs.kde.org/show_bug.cgi?id=350349
(and yeah, is a plasma4 bug, we have ported it 1:1 ;)

Comment 3 David Edmundson 2016-11-18 09:44:28 UTC 
Looks like it's the same as 361450 which I thought I'd fixed in Plasma 5.7.

Apparently not.
Comment 4 David Edmundson 2016-11-18 09:53:25 UTC 
In any case, we have an issue in Solid in general it's wrong to call finish() in the same event as creating a KJob, as no-one would have had a chance to connect to anything. From what we see in this stacktrace that must be happening here.

I'll try and see if we can fix this at the root in solid.
