Bug 483251

SUMMARY
The “open separate terminal window here” option in Tools menu does no longer work in Dolphin 6.


STEPS TO REPRODUCE
1. Run `dolphin` from a terminal (needed to see console output)
2. In the Dolphin windows, select Tools > Open separate terminal windows here


OBSERVED RESULT
Dolphin prints the following to stdout:
```
Detected locale "C" with character encoding "ANSI_X3.4-1968", which is not UTF-8.
Qt depends on a UTF-8 locale, and has switched to "C.UTF-8" instead.
If this causes problems, reconfigure your locale. See the locale(1) manual
for more information.
qt.qpa.xcb: could not connect to display 
qt.qpa.plugin: From 6.5.0, xcb-cursor0 or libxcb-cursor0 is needed to load the Qt xcb platform plugin.
qt.qpa.plugin: Could not load the Qt platform plugin "xcb" in "" even though it was found.
This application failed to start because no Qt platform plugin could be initialized. Reinstalling the application may fix this problem.

Available platform plugins are: minimal, wayland, eglfs, xcb, linuxfb, minimalegl, vkkhrdisplay, wayland-egl, offscreen, vnc.
```


EXPECTED RESULT
A new window of Konsole opens
