Yes, it's an X thing. xpra forks and execs Xvfb. I can reproduce the
error simply:

$ strace -olog -f Xvfb :100

XKB: Failed to compile keymap
Keyboard initialization failed. This could be a missing or incorrect
setup of xkeyboard-config.
(EE)
Fatal server error:
(EE) Failed to activate core devices.(EE)


$ grep -B1 "XKB:" log
3967  open("/nix/store/7imzw34rvqja8dmqxl3xjgrlhl9z8hb2-xorg-server-1.14.5/share/X11/xkb/rules/evdev",
O_RDONLY) = -1 ENOENT (No such file or directory)
3967  write(2, "XKB: Failed to compile keymap\n", 30) = 30


I can see some "share/X11/xkb/rules/evdev" in the xkeyboard-config package:

/nix/store/xz7sjgcac21c1brjmj79555wfsjv6lpm-xkeyboard-config-2.8/share/X11/xkb/rules/evdev

Now if I only knew how to make Xvfb find the evdev stuff from the
xkeyboard-config package.... Looking at xlibs.xorgserver ./configure
--help output...
