How to paste text into the Gimp text tool (copy and paste)

At least on Mac OS X, if you want to copy text from one source and paste it into Gimp inside a Gimp text tool text region, you’ll find that this doesn’t work with the usual Control-V (Command-V on the Mac) keystroke. In short, the secret solution is to right-click inside the text tool area and select “Paste” from the popup menu. I have no idea why the normal copy and paste approach doesn’t work in Gimp, but I do know that this approach works, at least with Gimp 2.8 on Mac OS X.
