Description Peter Andreasen 2015-05-19 07:46:25 UTC

Description of problem:
On my dual screen setup I try to select Folder View instead of default desktop. On the right monitor it worked, but I can not set the left (default) screen to folder view, every time I try, plasma just crashes and restarts. The desktop also randomly crashes and restarts during normal use.

Version-Release number of selected component (if applicable):
Fedora 22. 
plasma-workspace 5.3.0-5

How reproducible:
Always

Steps to Reproduce:
1. Log in
2. Change my default screen from "desktop" to "folder view"
3. Click Ok

Actual results:
plasma desktop crashes and stays with "desktop" view

Expected results:
To be able to change desktop

Additional info:
Desktop also randomly crashes during use (every 2 minutes) and restarts, but eventually causes a complete system crash.

Comment 3 Peter Andreasen 2015-05-21 19:53:30 UTC

I have updated to plasma-workspace 5.3.0-6.fc22.x86_64
The plasmashell crashes when I select folder view, background = slide show, then select folder with wallpapers = ~/.kde/share/wallpapers

Comment 4 Jan Grulich 2015-05-21 20:19:57 UTC

I was not able to reproduce this issue on any of my two laptops. Could you re-check whether this issue is gone when you downgrade to plasma-workspace-5.3.0-4?

Comment 6 Peter Andreasen 2015-05-25 16:30:15 UTC

I updated the packages as listed, but it gives me the same error. 

Application: Plasma (plasmashell), signal: Segmentation fault
Using host libthread_db library "/lib64/libthread_db.so.1".

The steps to trigger the crash are:
From cashew menu select "Settings for folder view" - Background image - Add folder...

Also, just opening the Background image tab and pressing OK (no images are selected) causes the crash.


The crash happens both on my desktop and in a Virtualbox machine.

Oddly enough, after each crash, Firefox no longer responds to the mouse scroll wheel.

Comment 7 Rex Dieter 2015-05-25 17:40:03 UTC

Can you give a more complete backtrace?

Comment 8 Peter Andreasen 2015-05-25 17:49:34 UTC

Update: It is now possible to change the background in Folder View to an image but "slideshow" and then "select folder" still makes it crash.


Backtrace - I can install the debug packages is I need to?

Plasma crash

Comment 10 Rex Dieter 2015-05-26 01:15:17 UTC

Adjusting summary to make it clear this is (now) about selecting a folder for backgrounds.

Comment 11 Maximilian Rehkopf 2015-06-01 22:55:54 UTC

I am affected by the exact same bug. As soon as "Slideshow" is set, you cannot get out of the "Desktop Settings" or "Folder View Settings" dialog unharmed (lest you click Cancel).
It might be worth noting that a fresh install from the F22 KDE Spin ISO does not expose the issue, it works as expected. Only after a subsequent "dnf update" did the issue show up.

Comment 12 Peter Andreasen 2015-06-03 11:11:10 UTC

After a recent update it has now changed behaviour; now the "Layout" drop down has been disabled so I can not change away from "Desktop" view. If I select "Slideshow" background and add a folder of wallpapers, it is not saved when I close the dialog.

Comment 13 Fedora Update System 2015-06-04 20:20:09 UTC

f22-kde-theme-22.3-1.fc22, plasma-desktop-5.3.0-6.fc22, plasma-workspace-5.3.0-8.fc22 has been pushed to the Fedora 22 stable repository.  If problems still persist, please make note of it in this bug report.

Comment 14 Peter Andreasen 2015-06-07 14:15:52 UTC

Problem persists for me.

Comment 15 Rex Dieter 2015-06-07 17:34:01 UTC

Problem this bug changed from the initial report (the initial problem was fixed), but the later one about selecting folder for slideshow is not.

Re-opening.

I see no upstream (bugs.kde.org) report about that yet (but I didn't search very hard).

Comment 16 Peter Andreasen 2015-06-12 13:28:21 UTC

Update: 
plasma-desktop-5.3.1-3.fc22.x86_64

Now the desktop lets me select folder view, and also lets me select a folder for slide show. However, only one monitor on my dual monitor desktop keeps the setting, and the other one (the primary) falls back to desktop view.

Comment 17 Fedora End Of Life 2016-07-19 14:09:36 UTC
