Bug 514400

SUMMARY

For keyboard shortcuts, `/home/user/Assets/Scripts/ww-run-raise/ww -f "zen-beta" -c "zen" -p "zen "` doesn't work nor shows any error messages / notifications. The command works in bash. I asked for help in multiple places and no one figured it out: the script must have a file extension like `.sh` to work: `/home/user/Assets/Scripts/ww-run-raise/ww.sh`.  

STEPS TO REPRODUCE
1. Download [ww-run-raise](https://github.com/academo/ww-run-raise).
2. Create a shortcut in Settings > Keyboard > Shortcuts, with the following for `command`: `/home/user/Assets/Scripts/ww-run-raise/ww -f "zen-beta" -c "zen" -p "zen "` *(without using the choose file button)*
3. Assign a keyboard shortcut. 

OBSERVED RESULT

Nothing happens, no error messages or notifications when doing all the steps above, but the command doesn't work.

EXPECTED RESULT

I think one of the following should happen:

1. The command should work if it calls a valid shell script (with a shebang in it), even if there's no file extension.
2. KDE shows an error somewhere if the command is not valid, maybe a message in the "Edit Command" box after entering in the command, or a notification. 

Right now if the file has an extension but the path is invalid, I get an error notification like so: `Could not find the program '/home/user/Assets/Scripts/ww-run-raise/wwdd.sh' `
