Comment 1 Julian Steinmann 2018-10-18 18:21:35 UTC

I cannot reproduce this crash. I did the following actions:
1. Right-click the toolbar and select "Configure Toolbar"
2. Select the "Delete" action on the right and click "Change icon"
3. Choose a random icon
4. Press "OK" twice (once for the icon selector and then for the "configure" dialog)

Did you do anything else? Also, it'd be great if we had a complete backtrace (= with debug symbols), as I currently think that this crash occurs in the Icon selector and not within Dolphin.

Comment 3 11wallace11 2018-10-18 20:37:25 UTC

Since I'm on Arch, it's quite difficult to get a full backtrace info as mentioned here: https://community.kde.org/Guidelines_and_HOWTOs/Debugging/How_to_create_useful_crash_reports#Preparing_your_KDE_packages
I did find out that by changing from Adapta icon set to Breeze icon set in theme settings solved this problem.
