Thanks for the bug report. Looks like an issue in the KUrlNavigator class, so I'll reassign the report there. Is the problem reproducible for you? If yes, a Valgrind log would be very helpful. See https://community.kde.org/Dolphin/FAQ/Crashes for details. Thanks for your help!

Crash in old unmaintained KF4 software with no duplicates from any Qt5/KF5 versions. If anyone can still reproduce using recent KF5 versions of KIO and Dolphin, please file a new bug. Thanks!
