When I try to start it on another konsole window I get QCommandLineParser: argument list cannot be empty, it should contain at least the executable name Only if i end the process with Ctrl+C I am able to restart konqueror.
A workaround, working at here, Konqueror settings > Performance > Disable the 'Always try to have one preloaded instance'. Earlier: KDE Forums - https://forum.kde.org/viewtopic.php?f=309&t=142697
That does the trick (this time). But as you said this can only be a workaround.
