Dear Maintainer,
Sep 23 09:58:10 leopard gnome-software[3304]: FIXME: Unknown progress handling
is not yet implemented for GsProgressButton

This crashing line above would point to function
fu_uefi_dbx_signature_list_validate.
There it possibly wanted to output the message "failed to get checksum for %s:
%s".
Kind regards,
Bernhard
