Description fawfulized 2018-10-30 17:52:47 UTC

Application: plasmashell (5.14.2)

Qt Version: 5.11.2
Frameworks Version: 5.51.0
Operating System: Linux 4.18.15-1-default x86_64
Distribution: "openSUSE Tumbleweed"

-- Information about the crash:
Tried to change the icon displayed on a desktop shortcut (desktop in "Folder View") by right-clicking it, selecting "Properties", and clicking the icon displayed in the upper left area of the "General" tab of the "Properties" dialog. Plasma crashes as soon the icon is clicked.

(Expected behavior: Display another dialog which shows system icons and allows to select a custom image to use as an icon).

Crash can be reproduced every time by clicking the icon in the properties dialog. Every single desktop shortcut can be used to cause a crash this way.

The crash can be reproduced every time.

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

Please install debug symbols for KIconThemes and reproduce

Comment 2 fawfulized 2018-10-30 18:38:06 UTC

I'm sorry it took this long (not very Linux-savvy and had trouble finding the debug symbols), but here is another crash with debug symbols for KIconThemes installed:

More interestingly, when a new, empty folder is created on the desktop, Plasma does not crash when trying to change the icon for that folder. The icon selection dialog appears normally, but Plasma crashes as soon as the entry "Applications" is selected from the drop-down next to the "System icons" option (in the Group "Icon Source").
