For the moment we can distro patch my workaround to avoid crashing. I'm
already working to understand the true problem and propose the proper

 As of an upgrade to 3.25.91 (last session that did not exhibit this
 behavior was a 3.24.x session), I've experienced several crashes of
 the shell in the overview. journalctl shows the following output at
 the time of the crash:
