SUMMARY
After updating frameworks to 5.70, if I set up an application to launch in the terminal through the application editor that edits .desktop files, the application will fail to launch, with message "Could not find the program 'konsole'".

STEPS TO REPRODUCE
1. Right click the application launcher in the taskbar.
2. Select "Edit Applications"
3. Create some application that would execute some file in your computer or similar, through the button "New Item".
4. Configure said application to launch in the terminal by clicking it, selecting the tab "Advanced" in the right pane, and ticking "Run in terminal".
5. Save the entries through the save button at the top.
6. Search for the newly-created entry in the applications menu, and click it to launch it.

OBSERVED RESULT
Shows a pop-up with error message "Could not find the program 'konsole'".

EXPECTED RESULT
Should launch a new konsole terminal in which the application is then executed, like it was doing in previous versions.
