Debug log

TL;DR: RDP compositor fails with “unable to checkDescriptor for {RDP peer
context address}”

Operating system: Debian GNU/Linux 7.2 (wheezy)

Manually compiled components:
FreeRDP commit d2a9df1ce0 (last commit on stable-1.1 branch as of this writing)
xkbcommon 0.3.2
Mesa 9.2.3
Wayland 1.3.0
Weston 1.3.1

I have tried using xfreerdp, rdesktop and Microsoft's Remote Desktop
application for Mac OS X as clients. When connecting, Weston logs “unable to
checkDescriptor for {RDP peer context address}” and nothing else happens. When
I connect a second time, Weston crashes due to a double-free. From looking at
the code I *think* it's an issue in the interaction between the RDP compositor
and FreeRDP, but I'm not sure. Below you find the standard output. A debug log
is attached.
