Menulibre/Menu Editor problem

Hi. I am not able to open Menu Editor aka Edit Applications in the Whisker Menu right click menu. There is an option somewhere in XFCE that controls this and I am determined to figure it out.

It is in Properties- Commands Tab- Edit Applications. See Screenshot:

That option is ticked with the appropriate command however it still does not open. I am not at home at the moment so I can’t verify. I will check when I can.

I have uninstalled Menulibre and see what happens when I reinstall.

Sorry for the double post.

I have reinstalled Menulibre and it still does not work. There must be a setting somewhere in XFCE. I know it works as whenever I reinstall Manjaro, Menu Editor opens up.

I am prepared to reinstall Manjaro to see which setting it is if it comes to it.

Have you tried starting it in terminal? What’s the output of:

This is what I get from the terminal:

(menulibre:5932): Gtk-WARNING **: 22:37:07.158: Locale not supported by C library.
	Using the fallback 'C' locale.

(menulibre:5932): Gtk-WARNING **: 22:37:07.827: gtk_menu_attach_to_widget(): menu already attached to GtkMenuButton

Looks different from my working one. Maybe forcing a reinstall including the python dependencies but can’t help you any further, it’s well above my abilities.

Other than that there’s this workaround: The Menu Editor (menulibre) is not launching. What else can I try?

to me it looks like a locale problem
(the first and the last line of the posted terminal output)

Verify that there is no problem there.

The workaround works. Thank you.

I did see that before posting however I would like to use the official editor included in the ISO by Manjaro rather than an external/additional download.

It seems like it is a locale problem, or it could be a problem with python as 6x12 suggests. Menu Editor works on a fresh install so it seems a bit weird to me that it could be a locale problem or even a python problem.
