Thank you for taking the time to report this bug and help make Ubuntu better. Unfortunately, we cannot work on this bug because your description didn't include enough information. You may find it helpful to read 'How to report bugs effectively' http://www.chiark.greenend.org.uk/~sgtatham/bugs.html. We'd be grateful if you would then provide a more complete description of the problem.

We have instructions on debugging some types of problems at http://wiki.ubuntu.com/DebuggingProcedures.

At a minimum, we need:
1. The specific steps or actions you took that caused you to encounter the problem.
2. The behavior you expected.
3. The behavior you actually encountered (in as much detail as possible).

Thanks!

Found finally a solution:

https://help.ubuntu.com/community/xrdp

I propose to add this to the package to be able to solve it.

This part was the Key:
 Next, create a polkit configuration file:

sudo nano /etc/polkit-1/localauthority.conf.d/02-allow-colord.conf

and input inside it:

polkit.addRule(function(action, subject) {
if ((action.id == “org.freedesktop.color-manager.create-device” || action.id == “org.freedesktop.color-manager.create-profile” || action.id == “org.freedesktop.color-manager.delete-device” || action.id == “org.freedesktop.color-manager.delete-profile” || action.id == “org.freedesktop.color-manager.modify-device” || action.id == “org.freedesktop.color-manager.modify-profile”) && subject.isInGroup(“{group}”))
{
return polkit.Result.YES;
}
});

Finally, restart xrdp and you should be able to connect:

sudo /etc/init.d/xrdp restart

Could you describe what you are trying to do exactly to trigger those errors? How did you configure xrdp? what server and client softwares do you use?
