[Bug 1723272] [NEW] apport-bug unable to init server, dumps core

[Paul]

Public bug reported:

After upgrading to 17.10, apport-bug fails with the follow error:

# apport-bug
No protocol specified
Unable to init server: Could not connect: Connection refused
No protocol specified
Unable to init server: Could not connect: Connection refused
Segmentation fault (core dumped)

Calling apport-cli directly works just fine. The problem seems to be a
general Xwayland permission issue, since nothing can connect to the
display server if sudo/su is used:

$ sudo xclock
No protocol specified
Error: Can't open display: :0
$ xauth list
xauth:  file /home/user/.Xauthority does not exist

If that's the way things are going to be in Ubuntu from now on, we need
to make apport-bug a bit smarter in the way it decides whether to use
the GUI version or not.
