As originally reported mailing list (this is a separate issue from the rest of the thread which is recorded in #92).
Just for fun I ssh'd to my server and ran '
xpra attach :100' locally and back through my ssh tunnel.
The letter A/a worked on that. But when I backspaced to my prompt
(which I think would cause a BELL), xpra attach died with:
$ xpra attach :100 Xlib: extension "RANDR" missing on display "localhost:12.0". cannot import dbus.glib notification wrapper: org.freedesktop.DBus.Error.ServiceUnknown: The name org.freedesktop.Notifications was not provided by any .service files mmap enabled using /tmp/xpra.k81xUq.mmap disabling compression Attached (press Control-C to detach) The program 'xpra' received an X Window System error. This probably reflects a bug in the program. The error was 'XkbBadKeyboard'. (Details: serial 807 error_code 143 request_code 140 minor_code 3) (Note to programmers: normally, X errors are reported asynchronously; that is, you will receive the error a while after causing it. To debug your program, run it with the --sync command line option to change this behavior. You can then get a meaningful backtrace from your debugger if you break on the gdk_x_error() function.)
