Application: plasmashell (5.2.2)

Qt Version: 5.4.1
Operating System: Linux 3.19.0-59-generic x86_64
Distribution: Ubuntu 15.04

-- Information about the crash:
I just upgraded a remote system with KUbuntu 15.04. The plasma window manager works fine with a monitor local to the machine. When I attempt to open a Remote Desktop connection from MS Windows 7 with this version of plasma + VNC indicates that Plasma has crashed. Remote Desktop worked fine with the previous version of the distribution and KDE worked fine as well.

With the previous Kubuntu distro I was using XRDP as the server for remote desktop. Since this was an upgrade I am assuming XRDP is still the server. This is validated by the fact that MS Remote desktop actually gets an XSESSION connection screen from the server. The issue only arises after the login has happened.

The crash can be reproduced every time.
