I have not managed to find a pattern yet, but occasionally, when I try to start konsole, nothing appears to happen; launch feedback occurs, but no window opens, and no error messages are displayed. This occurs if I tried to start Konsole via a launcher or the Run Command dialog (Alt+F2). However, if I start Konsole from a shell in xterm, it works fine. When this occurs, "$ ps -e | grep -i konsole" shows several instances of Konsole, most of which (IE: at least half) are defunct. After "$ killall konsole", I can start Konsole from the launchers again. "# journalctl -f /usr/bin/konsole" only shows the following: May 01 07:00:17 ares konsole[22752]: QCoreApplication::arguments: Please instantiate the QApplication object first May 01 07:00:17 ares konsole[22753]: QDBusConnection: session D-Bus connection created before QCoreApplication. Application may misbehave. May 01 07:00:17 ares konsole[22752]: QDBusConnection: session D-Bus connection created before QCoreApplication. Application may misbehave. This seems unrelated as it occurs every time I start konsole, successfully or not. This message also shows in the shell if I start konsole via xterm. Reproducible: Sometimes Steps to Reproduce: 1. Start Konsole via a launcher (Kickoff, desktop icon, panel launcher, etc) or Run Command dialog. Conditions causing/triggering bug are unknown as of this report. Actual Results: Launch feedback occurs, no window is opened, no error messages displayed. Effectively, nothing seems to happen. Expected Results: Konsole should start normally. Version 3.0.1 Using KDE Frameworks 5.9.0 BASH v4.3.033 Plasma Desktop version is 5.2.2 In the off chance it matters, $ uname -a : Linux ares 3.18.11-1-MANJARO #1 SMP PREEMPT Sat Apr 4 21:48:56 UTC 2015 x86_64 GNU/Linux Listing bug as "Minor" due to ease of "killall" work-around and obviousness of incorrect behavior.

I have this bug on Kubuntu 15.10 with KDE 5.5.3, QT 5.5.1, KDE Frameworks 5.18.0 But, I can start konsole by using Xterm or Uterm with many konsole process zombie.
I also see this, with kubuntu 15.10 running as a vbox guest. konsole 15.0.8.0 kde frameworks 5.15.0 qt: 5.4.2 It happens if I try to launch from within the VBox instance, or even if I ssh -Y in from the host (Gentoo). Doing a ps from that ssh session often seems to show some drkonqui instances, but I can't figure out how to get the full information from any of them. In the KUbuntu - if I do Alt-Tab, I can see the konsole instances with a square frown face icon, but nothing actually shows up as a visible window.
