I cannot use gtk with qemu in beowulf. I get:

qemu-system-x86_64 -display gtk
Failed to open module: /usr/lib/x86_64-linux-gnu/qemu/ui-gtk.so: undefined symbol: qkbd_state_lift_all_keys
qemu-system-x86_64: Display 'gtk' is not available.

The installed qemu* packages are:

  qemu                  1:3.1+dfsg-8+deb10u5 amd64     
  qemu-system-common    1:3.1+dfsg-8         amd64        
  qemu-system-data      1:5.0-6              all
  qemu-system-gui:amd64 1:5.0-6              amd64
  qemu-system-x86       1:3.1+dfsg-8         amd64
  qemu-utils            1:3.1+dfsg-8+deb10u5 amd64

I tried to downgrade qemu-system-gui to 1:3.1 but didn't help.

In ceres (schroot) using gtk works with no problems. When checking the
installed qemu* packages, all version numbers were 1:5.0-6.
