Public bug reported:
When the screen is locked, typing anything on the keyboard doesn't lead
to the password prompt. Instead, the desktop / open applications are
shown for a few seconds, but the session is not unlocked, the gnome-
shell crashes and the lock screen is back on. After that, the kernel log
says:
[ 1253.059365] traps: gnome-shell[15914] trap int3 ip:7fa53d1000d5
sp:7fffdf2bbc50 error:0 in libglib-2.0.so.0.6400.0[7fa53d0c4000+84000]
If libreoffice is open during this procedure, it is killed. The kernel
log says:
