I will now delete the .DCOP files in my home directory

<br>
OK I have deleted the files, but still cannot print , same error

I will now log out and log back in again ........................<br>

As expected the printing now works again.<br>
<br>
I am at a loss to explain this behaviour, but it is extremely annoying.<br>
Kprinter is a useful tool, but if this continues I will need to find a
work around to avoid using it.<br>
<br>
All the best<br>

I have only three .DCOP* files _0, _1 and _2 with corresponding ":"
files.<br>
<br>
All owned by the user.<br>
<br>
I deleted them all and re-logged in and kprinter is now working again.<br>
<br>
I normally have two sessions running, which would probably explain why
there was a 0 and a 1 file.<br>
<br>
So the handles were the cause, and the fact that they were not
destroyed at termination was the problem. But I have been using Linux
for several years, upgraded more times that I wish to remember and
never had this problem before with kprinter. I therefore think that
something has probably changed somewhere which has caused this effect.<br>
<br>
Since I use Mandriva 2007 and Kurt was on Suse 10.0, I would not
presume that it is a distro problem.<br>
<br>
I will report back if this happens again<br>
<br>
Many thanks Kurt for solving this, and to everyone for their help.<br>
<br>
All the best<br>

<pre wrap="">OK, I was able to run a (very short test).
1. created a new (non-root) user; this user can print with kprinter
without any problem
2. the user that had problems with KDEPrint still can't print; same
problems as before. In addition, this user now does not even see
kdeprintd listed any more underneath "kded" when he runs "kdcop"
(the GUI to dcop) -- and the command "dcop kded kdeprintd" now
does return:
"object 'kdeprintd' in application 'kded' not accessible"
Strange.
I've no idea what's going on. But later I'll move away ${HOME}/.kde
for the user with the problem and let him start a virgin KDE session
(previously I had already tried that with the two files kdeprintrc &
kprinterrc in ${HOME}/.kde/share/config/ on their own, but that did
not help...).
But I can't do that right now, sorry.
Cheers,
Kurt

<pre wrap=""><!---->
It works now again.
I have noticed a *lot* of files with the following scheme for their
names, all in $HOME of the said user:
.DCOPserver_myhostname_:NNN -> .DCOPserver_myhostname__NNN
.DCOPserver_myhostname__NNN
(where the filename with the ":" was always a symlink pointing to the
one with the replacement "_", and where "NNN" was a figure ranging
from "0" to "255").
I'm not sure what caused the creation of all those files, but somehow
there seemed to be a limit of 2^8=256 to their number.
I deleted them all but the ones with "0", logged out of KDE and back
in, and now kprinter works again.
Will be watching if anything does re-create those files. So far I've
only the "*_:0" and "*__0" files here.
Cheers,
Kurt
