Using XFCE's Spanish translation, the contextual menu for Panel buttons shows
"Remover" for "Remove". "Remover" actually means to stir or mix, and the correct
translation should be something like either "Quitar" or "Eliminar". 

I'm sorry if this isn't the right place to post translation mistakes.

Reproducible: Always
Steps to Reproduce:
1. Use Spanish translation
2. Right-click on a panel item
3. Read contextual menu

Actual Results:  
The menu option for removing the item shows "Remover"

Expected Results:  
It should say either "Quitar" or "Eliminar"
