Comment 7 for bug 1829826

to have a "clean" way to reproduce the bug:

-Create a new component
-Select the reference
-press "E" to edit it

then:

Thread 1 "kicad" received signal SIGABRT, Aborted.
__GI_raise (sig=sig@entry=6) at ../sysdeps/unix/sysv/linux/raise.c:51
51 ../sysdeps/unix/sysv/linux/raise.c: File o directory non esistente.

Backtrace gives:
