How reproducible:

Every time.   It worked yesterday, but I can't find anything in yum.log related to KDE or X11.

Steps to Reproduce:
1. ssh [-X] me@server | root@server
2. dolphin | konqueror 
(I am testing Samba, so its nice to be able to open those apps on the server)

  
Actual results:

$ dolphin
unnamed app(1745): KUniqueApplication: Cannot find the D-Bus session server:  "/bin/dbus-launch terminated abnormally with the following error: Autolaunch error: X11 initialization failed.
" 

unnamed app(1744): KUniqueApplication: Pipe closed unexpectedly. 

$ konsole
unnamed app(1748): KUniqueApplication: Cannot find the D-Bus session server:  "/bin/dbus-launch terminated abnormally with the following error: Autolaunch error: X11 initialization failed.
" 

unnamed app(1747): KUniqueApplication: Pipe closed unexpectedly.

However, 

$ xterm
xterm Xt error: Can't open display: 
xterm:  DISPLAY is not set

Not sure if that is a cause or effect.


Expected results:

Graphical apps should run on the client.


Additional info:

This is happening for all clients, for multiple servers.  Both the clients and the servers worked yesterday.

This bug is related to https://bugzilla.redhat.com/show_bug.cgi?id=699238.

I posted my info there as well.

Comment 1 Linuxguy123 2011-09-28 17:14:11 UTC

For some reason it works now.

I'm sure I tested ssh -X me@server before and it failed.  But now it works with ssh -X me@server.

I'm closing it for now.  I'll open it if it reappears.
