Description Martin Koller 2017-01-14 17:13:20 UTC 
Application: plasmashell (5.8.3)

Qt Version: 5.6.1
Frameworks Version: 5.26.0
Operating System: Linux 4.9.1-1.g1072b39-vanilla x86_64
Distribution: "openSUSE Leap 42.2"

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

I wanted to modify the systemloadviewer code, copied it to my $HOME, just commented a block, installed it via plasmapkg2 -i .
Then I wanted to add it again, opened the "add new widget" dialog thingy and could not select it (greyed out). If iltered on "load" and tried to add another widget - the "CPU load monitor". When clicking/double clicking on it, plasma crashed

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

does it match with the folder name?
Comment 4 Martin Koller 2017-03-17 15:27:41 UTC 
$HOME/.local/share/plasma/plasmoids/org.kde.plasma.systemloadviewer_martin
Comment 5 Martin Koller 2017-12-17 11:02:19 UTC 
Since I already have my own desktop shell, liquidshell, I don't care any longer.
