When started, Proof General splits the screen in two:
| | |
| | |
| User's file | Message log |
| | |
| | |
Each time a message is received, it's displayed in the Message log window.
My extension sometimes reuses that window for other things (for example, to show company-mode's documentation buffer).
The set-window-buffer call is there to ensure that the user sees new messages. Of course in most cases that call is useless: that's why predicating it on the window not already displaying the message log makes things faster.

Somewhat unclear. The OS are the same (Linux mint), and the problem does happen in emacs -Q for the other user. The version of Emacs is the same.
