It isn't about a specific key. This message is basically saying we don't
know what keymapping the X server is using, so we've given up. Historically
QEMU could only identify evdev and/or kbd key mappings. With the newly
merged code, we can now detect many more especially including Windows and
OS-X X11 server mappings. So git master hopefully removed the most common
cases that would trigger this particular error message. There's probably
still some remaining though, as there's a huge range of X11 servers impls
in the world.  With current git master this message will instruct the user
to provide us a list of relevant info to help us diagnose it - see the
end of ui/x_keymap.c file.
