SUMMARY When opening konqueror, the browser comes up then displays an error message: Unknown error code -1220020144 Please send a full bug report at https://bugs.kde.org STEPS TO REPRODUCE 1. Start konqueror 2. 3. STEPS TO REPRODUCE: It seems like changing the default home page causes konqueror to start with an error message, or just crashes. OBSERVED RESULT The browser somehow works but when trying to change preferences in the Settings - Configure Konqueror menu only the Performance and Bookmarks are displayed. EXPECTED RESULT The browser should work all the time and offer to change all settings.
