GIMP 2.10 crashes when copying and pasting pixels

[Damian Yerrick]

I was copying and pasting a thin (152 by 2 pixels) rectangular area in a small (160 by 144 pixels) image in GIMP 2.10.36 on Xubuntu 24.04 on a Lenovo ThinkPad T450 laptop with an Intel Core i5-5300U CPU and 8 GB of RAM. I got a crash. After restoring the session and repeating the copy and paste, I got the same crash.

To reproduce:

1. In GIMP, create a new image 160 by 144 pixels
2. Choose Rectangle Select tool (press r)
3. Zoom in for the following steps
4. Drag a rectangle with upper left corner (4, 134), width 152 pixels, height 2 pixels
5. Ctrl+C, Ctrl+V

I expected the image to bee based onto a new floating selection; instead I got a crash.
