Followup-For: Bug #932088

Dear Maintainer,

I meet the same bug.

I use Buster 10.7, I installed XFCE,MATE,GNOME desktop in my computer.

But this bug only occur in XFCE, MATE and GNOME is no problem.

BTW:
dbus-x11 is already installed in my compurter.

I also strace the pid of gdebi-gtk, the last error lines is following:

Is this bug possible have relation to the selinux ?

I'd installed the package about selinux:

 dpkg -l|grep selinux
ii  libselinux1:amd64                    2.8-1+b1                                     amd64        SELinux runtime shared libraries
ii  libselinux1:i386                     2.8-1+b1                                     i386         SELinux runtime shared libraries
