Konqueror failing to start from root shell

Allright. When I'm at it I might as well see if anyone knows the sollution to this problem. When trying to start konqueror fas root from a shell it starts and then imediately exits and I receive the following message in the shell.

mcop warning: user defined signal handler found for SIG_PIPE, overriding
/tmp/mcop-[username] is not owned by user

and a little bit later

Mutex destroy failure: Device or resource busy

Have anyone experienced something like this before? It starts like a charm when started by a regular user. Same thing happens when I start the "File Manager -Super User Mode" from the start menu, but without the error messages being printed to some terminal. I'm running KDE 3.1.

Am I the only one who have experienced this. I have now installed RedHat 9 on 5 computers with different hardware, and it's the same on every one of them. So I have ruled out that it was a hardware or installation issue. The only thing left to blame is RedHat itself...

Mutex destroy failure: Device or resource busy

The same happens to me if I work in superuser mode.
After I exit from KDE application the error message appears:
"Mutex destroy failure: Device or resource busy"

It is interesting that I don't have any error messages
if I start KDE applications as a normal user.

I have Red Hat 9 Linux installed on my Intel Pentium 4.
My Friend has the same problem but he has AMD
computer with new distro of Mandrake.

So, this problem is a kind of a bug in KDE 3.
I searched in the Internet and found that many
people have the same problem but I did not see
any suggestion that could solve this.

I had exactly the same problem when I used RH9, though now I use mandrake 10 and konqueror works.
The way I solved it was to run ssh server on my computer and instead of using su for superuser, i logged in using ssh to localhost. I think the command to do this is "ssh -l root localhost", so try this and see if it works.
If it doesn't maybe you will have to use "ssh -X -l root localhost" to forward X window connections.

It's not safe to run stuff as root anyways. Actually, it's very stupid, you shouldn't get in a habit of running things in root. Who knows if the program your running has a volunurability to aquire root privs

We are not talking about something special or complicated.
Such things like file managers and text editors should work
correctly regardless whether you are root or ordinary user.
If these applications produce errors it means that something is wrong
and should be corrected. And saying that it is not safe to run any
applications as a root is equivalent to saying that it is not safe
to run Linux.
