If you try to run the keyhandler script and you forget to give it execution permissions, mcomix3 fails to open the file silently (GUI-wise). There's an exception dump in the console but, for the most part, mcomix3 is run without a console.
Suggestion:
Make a dialog showing the PermissionError error happened and ask to add execution permissions to the script file (while showing the path to the file).
I tried doing this one myself but I still don't know how to make use of GTK and all other dialogs were much different than one for this purpose.
