The program crashes when starting any interactive session (except for a Scheme session). TeXmacs 1.99.18 Guix c5dc87f Guix System Linux gnu 5.10.14-gnu ## Steps to reproduce 1. Start TeXmacs from a terminal: LANG=C texmacs. 2. Create a new document: Press Ctrl+N (if there isn't one already). 3. Start an interactive Python session: In the main menu, Insert → Session → Python. ## Expected result A new Python input field is inserted in the position of the caret. ## Unexpected result The program crashes with the following error: ★★★★★★★★★★ LANG=C texmacs TeXmacs] With linked TrueType support TeXmacs] debug-shell, Launching 'python3
