Bug 362164

A Debian 8 system was established first with Gnome 3 as default desktop environment, then I switched to KDE. Then I installed xrdp 0.612 and vnc4server 4.11 from the standard Debian repository to access the system by a Windows 7 computer via Remote Desktop Protocol. In  "etc/xrdp/startwm.sh", the default line ". /etc/X11/Xsession", that would start Gnome,  was replaced by "startkde" to ensure also rdp users see the KDE desktop. Indeed, KDE was loaded, but produced a failure dialog box. Nevertheless, after closing the failure dialog box, KDE seems to work fine (except 3 unusual icons in the system tray).

Reproducible: Always

Steps to Reproduce:
1. Installation of xrdp 0.612 and vnc4server 4.11
2. Replacement of default line ". /etc/X11/Xsession" by "startkde" in "etc/xrdp/startwm.sh"
3. Rdp access from Windows 7 to xrdp (module "sesman-xvnc")

Actual Results:  
KDE starts with normal desktop, but also failure dialog box at the upper margin. After closing this failure dialog box, KDE seems to work fine. Despite of 3 unusual icons in the system tray, no differences in behavior were noted so far as compared to non-remote access.

Expected Results:  
KDE starts without failure dialog box and with normal system tray icons.

Failure dialog box content:
