Closed issue by patoski on void-packages repository

https://github.com/void-linux/void-packages/issues/14174

Description:
### System

* xuname:  
  *Void 4.19.69_1 x86_64 GenuineIntel uptodate rrFFFF*
* package:  
  *mate-menu-18.04.3_1 and mate-menus-1.22.0_1*

### Expected behavior
Clicking on the Advanced Mate Menu shows application menu.

### Actual behavior
Clicking on the menu (in a panel) displays an error:

> Traceback (most recent call last):
> 
>   File "/usr/lib/mate-menu/mate-menu.py", line 202, in PopulatePlugins
>     exec("from {plugin_module} import pluginclass".format(plugin_module=plugin_module))
> 
>   File "<string>", line 1, in <module>
> 
>   File "/usr/lib/python2.7/site-packages/mate_menu/plugins/applications.py", line 38, in <module>
>     import matemenu
>     ImportError: No module named matemenu
### Steps to reproduce the behavior
install mate-menu package
Right-click on a panel, Add to panel, and then add the MATE Menu. Click on the new MATE Menu in the panel.

This problem was mentioned in issue #12004 (mozo which works fine for me). Mozo was fixed by #12001 but mate-menu remains broken.
