https://github.com/void-linux/void-packages/issues/19075

Description:
<!-- Don't request update of package. We have a script for that. https://alpha.de.repo.voidlinux.org/void-updates/void-updates.txt . However, a quality pull request may help. -->
### System

* xuname:  
  *Void 5.4.19_1 x86_64 AuthenticAMD uptodate rrrmFFFF*
* package:  
  *xfce4-whiskermenu-plugin-2.4.0_1*

### Expected behavior
Right-click on any program in whiskermenu to bring up its context menu. Then click on any __external__ option (i.e. Firefox's private window). The option should be executed correctly.
### Actual behavior
Instead of executing the selected option, whiskermenu crashes and (in most cases) Xfce complains and brings up a dialogue to either remove or restart it.
### Steps to reproduce the behavior
Add Whiskermenu to Xfce's panel.
Open it.
Right-click on anything that has an __external__option.
Select such an option.
Crash.

Note:
Why __external__?
When you select something like "add to desktop" or "add to panel", the crash __doesn't__ occur.
