bug#33958: Gnucash 3.3 segfaults when pressing control key

[Maxim Cournoyer]

This occurs using GnuCash 3.3 from Guix
707efe171a4e0e542a7d969c130195fa94b5d615.

It seems the problem has to do with Guile. Here's the start of the
program until a triggered crash, and its backtrace (sorry, no debugging
symbols :-/).
