When you examine the trash-can, it will say,
"You browse through the contents of the trash-can bin..."
"It is empty"
I found this "trash-can bin" in the team rocket base in celadon city,
The errors are "trash-can bin" and it if you are browsing the contents of something it cant be empty or else there'd be no contents.
Not a major error but it is something to be fixed, do it when you have the free time.
