Do you see any pattern in which strings could be making X crash?  From
looking at the backtrace (ProcXkbSetMap calling _XkbSetMapChecks), it
would be when pasting characters which are not directly available in the

probably write a little program that reproduces brltty's behavior that
upstream can use to reproduce the issue.
