Hai,
when running yakuake, I am getting error message,

root@Slackware:~# yakuake      

<unknown program name>(5160)/: KUniqueApplication: Cannot find the D-Bus session server: "Did not receive a reply.
Possible causes include: the remote application did not send a reply, the message bus security policy blocked the reply, the reply timeout expired,
or the network connection was broken."
<unknown program name>(5159)/: KUniqueApplication: Pipe closed unexpectedly.

previously it was running. The only difference is , now I am trying as normal user, where as previously I used as a root user.
I tried with,

chmod 0777 yakuake

in /usr/bin directory.
but, no luck. Even I tried as a root used [ as shown in first code ] , that time also getting the error.
How can I solve this ? So far I can not find anything in google..

That sounds like a permission issue for the user your are using, did you read http://slackware.mirrors.tds.net/pub/slackware/slackware64-current/Slackware-HOWTO to determine which groups your user should belong in?

No. I did not read that.

But before reading this post , I re-installed the application as root then rebooted the system , application is running now in normal user mode . [ before, rebooting I tried to run, but same error I got ] . Sounds silly, but I want that application hardly. So, just gone by this blind method.

Since it is running now for the same conditions [ installing as root, running as normal user ] , I guess, there may be some other problem . Not sure. Because, on the same day, I got the message that my ALSA driver was not found in the bus. But, I will cross-check the user-group needed to run the application.

But, shell is a kind of editor. Not going to use any critical resource until changing user mode to root. Then , why is this limitation [users, belongs to some particular group can only use ] is made ?

What's the output?

Sorry Marc, I re-installed the application and now it is working fine. I have pasted , the current output below,
