Description Guilherme de Almeida Suckevicz 2022-02-09 19:06:02 UTC 
If the path to the temporary directory on Linux or macOS contained a space, this would break removal of the temporary image file after im.show() (and related actions), and potentially remove an unrelated file. This been present since PIL.
