I am running KDE 5.3 on Kubuntu 15. At a certain point I have started seeing this:



How do I get rid of those drkonqi entries on the bar?

This means quite some DrKonqi processes are around, but never showed up a crash dialog (in in return you never quit and thus keeping crashed processes with them)

=> This indicates some bigger trouble, but it's *likely* resolvable by just killing all drkonqi processes (from konsole or ksysguard, usually bound to ctrl+alt+del)
Watch out though, that not some formerly crashed process start running wild afterwards.
