[FreeNX-kNX] Problem running KDE applications in rootless sessions on Ubuntu 10.04 LTS (Lucid Lynx)

[Stefan Baur]

Hi list,

I'm having issues with sessions terminating unexpectedly when tring to 
run certain KDE applications.

Server:
Ubuntu 10.04 LTS (Lucid Lynx) with FreeNX installed via

debhttp://ppa.launchpad.net/freenx-team/ppa/ubuntu  lucid  main
deb-srchttp://ppa.launchpad.net/freenx-team/ppa/ubuntu  lucid  main

Client:
Windows 7 Home Premium with Nomachine NXClient 3.4.0-5

To debug the issue, I did the following:
Start xterm in rootless mode
Run "screen" in xterm
Run a regular SSH session (using PuTTY)
Connect the PuTTY session to the xterm-screen by issuing "screen -x"

Run "konqueror ~" in xterm
NX session aborts; the screen session in PuTTY shows the following messages:

> surfer1 at surfbox:~$ konqueror ~

> konqueror: Fatal IO error: client killed
> kdeinit4: Fatal IO error: client killed
> klauncher: Exiting on signal 15
> kded4: Fatal IO error: client killed
(here's where it crashes)

If I run a full-screen KDE session, it doesn't crash:

> IBusInputContext::createInputContext: no connection to ibus-daemon
(konqueror starts as requested, NX session stays active)

What's going on here? Any ideas? Is this a bug? Is there a workaround 
for rootless sessions and KDE applications?

Kind Regards,
Stefan
