Description Dan Ratje 2015-12-17 16:34:13 UTC
Application: plasmashell (5.5.0)

Qt Version: 5.5.1
Operating System: Linux 4.2.6-301.fc23.x86_64 x86_64
Distribution: "Fedora release 23 (Twenty Three)"

-- Information about the crash:
I wanted to change the background in time for Christmas, so I right clicked the desktop -> Desktop Settings -> click the "Open..." button. 
It failed several times.  Just now, while filing the report, it works just fine.  Go Figure....

The crash can be reproduced sometimes.

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

Comment 8 EMR_Kde 2016-01-07 15:43:40 UTC
I had been using another desktop environment because KDE was too buggy... oh just now, something else crashed while typing this. So sad... I love KDE but it's not ready.
Comment 9 Jason Elwell 2016-01-07 15:49:44 UTC
Please let me know what I can do to troubleshoot this.  I am a humble sysadmin, but given enough instruction, I should be able to provide what is requited.  

Kate has become because I cannot open any files.  I have turned off all compositing, and the issue remains.

Please help me help fix this.

Yeah, I am running Kate out of another desktop environment and it's weird... it stays up in the background, doesn't start when you want it to, freezes randomly. I've gone back to VIM :-\ 

In this case, I set my desktop to "Folder view" then as I was changing my desktop wallpaper. I clicked on "select file". Plasmashell crashed. Then something else crashed in the background, while I was writing the bug report!!

Don't know, don't care, I am not using KDE5 for now. I just logged in to check it out, and see how stable it was/would be. I guess my question was answered.

If you are on Fedora, try the qt5 update to 5.5.1 in updates-testing. I think this is fixed.
Comment 12 Jason Elwell 2016-01-07 16:40:54 UTC
sudo dnf -y upgrade qt5* kf5* --enablerepo updates-testing --refresh

qt5-qtbase.x86_64                            5.5.1-11.fc23    @updates-testing  
qt5-qtbase-common.noarch                     5.5.1-11.fc23    @updates-testing  
qt5-qtbase-gui.x86_64                        5.5.1-11.fc23    @updates-testing

No more immediate crashes!  Thanks!!!
Comment 13 Jason Elwell 2016-01-07 16:47:34 UTC
Sorry the correct command line doesn't require kf5*, thusly:

sudo dnf -y upgrade qt5* --enablerepo updates-testing --refresh

HOWEVER, something else (perhaps not this update, but this morning's) has broken kwallet5, but that's for another ticket.
