Description

Created attachment 89742 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.
