No expert but ./src/core/slaveconfig.cpp:199:MetaData SlaveConfig::configData(const QString &protocol, const QString &host) Seems to be keeping a cache, that might explain the not changing, the same code seems to be there in kdelibs though, does it work in konqueror based in kdelibs4? Even if it does, i guess you should gdb-debug that part both in kdelibs4- konqueror and in KF5-konqueror and see what's the difference.
