Bug#849342: [xrdp] xrdp-sesman: Fails to start Xorg

[Ben Armstrong]

Package: xrdp
Version: 0.9.1-1
Severity: normal

--- Please enter the report below this line. ---

After upgrading to 0.9.1-1, Xorg is no longer started when xrdp-sesman
runs. Downgrading back to xrdp_0.9.1~20161126+git589b29f-1 resolves the
issue.

Here's what is in journalctl -u xrdp-sesman after the failure:

I don't see an Xorg log in any of the usual places, so the reason for
the failure is obscure. I confirmed there was no Xorg :10 running before
each test, however. Let me know whatever other info you need and how to
obtain it. The issue is 100% reproducible for me.

I was very much looking forward to this release as I experience a number
of issues with prior releases, including not working with any android
RDP client, which I had hope this would help with:

    + Enables libpainter for clients not supporting drawing orders.
      + Fixes MS RDP client on Android and others.

No open source Android client works with xrdp (key mappings or pointer
or both are broken) and the MS client fails because of the issue the
above changelog entry addresses.

Thanks,
Ben
