[Bug 1373792] Re: Can't log in with one user, other user log in fine - "Could not start ksmserver, check your installation"

[C K]

Ok, I finally figured it out myself.

For others to replicate I describe how I did it. 
As I new that I could log into KDE with other user accounts I first moved all  hidden files ~/. to a new directory. Then I tried to log in and it worked. Next I started to move those files and folders back to my home directory ~/. 
Then I figured out that .profile was causing it, better said I checked into what was causing it. I saw that the inclusion of my ~/bin directory was the root of the problem. In that directory I have a lot of executables, I think most or all of them were copied by RVM (Ruby Version Manager). Then I furthermore drilled untill I finally found the causing file(s).

I had 3 dbus executables in there, that were probably outdated and
conflicted with newer libraries but were called by the /usr/bin/startkde
script.

The files were:

dbus-cleanup-sockets
dbus-deamon
dbus-uuidgen

The dbus-deamon was the one to remove to be able to log in again.

I have no idea when, how and why these files where copied into the ~/bin
folder.

Hope this will help others that experience the same.
