Hi,
Looks like today updates are trashing gnome almost completely.
gdm-x-session cannot setup XKB mapping. gnome-shell is core dumping ..
"journalctl -xe" output is in attachment.
If this is rawhide, you might try downgrading m17n-db* . On one machine the latest version is causing lots of applications to crash. On other machines it doesn't happen and I don't know what the difference is. I'm hoping the gcc8 rebuild will fix things when it happens. Right now I don't have much for the maintainer to go on to try to fix things.
m17n-db has nothing to do with xkb.
I've done something different.
I found that m17n-db is only required by m17n-lib package and m17n-lib is required only by ibus-m17n, and nothing requires ibus-m17n.
So I've removed all those three packages and after logout-> loging (under gnome or Xfce; both under X11) still gdm has been failing with *exactly* the same error messages.
xkb is about keyboard mappings withing working X11 server.
Nevertheless just found what is causing tose xkb errors.
I've installed xorg-x11-xkb-extras to have the access to setxkbmap command and on executing:
[tkloczko@domek ~]$ setxkbmap -v pl
Warning! Multiple definitions of keyboard layout

Summary : X Keyboard Extension configuration data
Description :
This package contains configuration data used by the X Keyboard Extension (XKB),
which allows selection of keyboard layouts when using a graphical interface.
As long as upgrade 2.23 has been done around the time when mine problems with xkb started I've downloaded xkeyboard-config-2.22 from f27 and after downgrade:
[tkloczko@domek ~]$ setxkbmap -v pl
Warning! Multiple definitions of keyboard layout
Using command line, ignoring X server
Trying to build keymap using the following components:
keycodes: evdev+aliases(qwerty)
types: complete
compat: complete
symbols: pc+pl+inet(evdev)
geometry: pc(pc105)
[tkloczko@domek ~]$ łóćźęśźż
So I'm able now to enter Polish characters :)
So looks like at least something is wrong with xkeyboard-config-2.23.
If no one will try to check what has been changed in 2.23 tomorrow will continue investigation (at the moment have no time to raise ticket).
A .. BTW: looks like m17n-{db,lib} and ibus-m17n are not needed and everything is working perfectly fine (doesn't matter am I using us, gb or pl xkb mapping).
Another conclusion: I think that using xkbcomp compile text definition to binary file and use those binary files is a bit over complication of setting all xkb settings.
setxkbmap command can use text xkb definitions and using libxkbfile library to set keyboard mapping is causing that this library lis dynamically linked with few other binaries which are constantly in memory. Using this library is not kind the RightUnixWay(tm) as setting keyboard mapping is done only one time per GUI session or change xkb settings is not time critical using external command is OK.
Additionally using fixed file name /tmp/server-0.xkm adds security risk. On use setxkbmap nothing needs to be written to any temporary file.
it is nothing wrong with do fork() end execute some external command.
If whole desktop would be using setxkbmap instead xkbcomp and libxkbfile it would be possible to change xkx setting from command line or do additional diagnostics like I've done above.
