Description GML 2006-04-06 12:29:02 UTC 
Version:           inconnu (using KDE 3.5.2, Debian Package 4:3.5.2-1 (testing/unstable))
Compiler:          Target: i486-linux-gnu
OS:                Linux (i686) release 2.6.15-1-686-smp

when I push left button mouse on an icon in desktop, kdesktop freezes.
I must kill and restart kdesktop.
I've no problem with the same takedown with konqueror in /home/gml/Desktop.
I've this bug since I've upgraded KDE to 3.5.2 version. My previous version was 3.5.1.
Comment 1 Philip Rodrigues 2006-04-06 16:29:52 UTC 
Run "kill -SEGV <pid-of-kdesktop>" to get a backtrace, and attach the backtrace here. Does the same freeze happen with a newly-created user?
Comment 2 GML 2006-04-06 19:22:46 UTC 
When kdesktop freezes, I've launched "kill -SEGV <pid-of-kdesktop>".
No backtrace appears, yet now kdesktop doesn't freezed when I push left button mouse on an icon in desktop.
Have you any idea ?
Comment 3 Philip Rodrigues 2006-04-06 23:53:10 UTC 
Do you mean that the problem has gone away?
Comment 4 Thiago Macieira 2006-04-08 12:28:08 UTC 
Problem looks like it has gone away.

PS: don't attach backtraces; paste them.
Comment 5 GML 2006-04-08 13:44:28 UTC 
The bug is always present when I restart kde.
Comment 6 Daniel Frein 2006-04-20 12:18:36 UTC 
I'm hit by this bug almost every day, but I found no way to reproduce it. Sometimes I had the feeling that this is a timing issue between the mouse-over popup window and a left mouse-button click or only appears by selecting icons which were just created seconds before a LMB click. but the bug also appears on "older" icons. the main problem with this bug is that it captures keyboard input. If I am not going directly to a console and "killall -9 kdesktop", but am moving my mouse around (kicker, kdesktop), in most cases no running app is able to get any further keyboard input. Therefore I have to kill kdesktop in these cases solely with the mouse, usually with ksysguard because there is an entry in kmenu and it does not need keyboard input. I'm sure that this regression was not present in KDE-3.5.0.

I'm using kubuntu dapper; Qt: 3.3.6; KDE: 3.5.2; KDesktop: 3.5.2
Comment 7 Daniel Frein 2006-04-20 12:24:15 UTC 
sorry, some left-right confusion in by brain during the above posting; mostly kdesktop crashes during a right-click to open the context menu...
Comment 8 Justin Sheckler 2006-04-28 16:50:01 UTC 
I can confirm this behavior with 3.5.2 on SuSE10.  Have only noticed it with right-button clicks.  Trying to kill the KDesktop proc usually freezes all of KDE, so now I just ctl-alt-backspace and login again.  Happens about once a day.
Comment 9 GML 2006-05-06 20:03:43 UTC 
Please to correct this, I can't use my desktop.
I wish help you for debug this.
How I track this bug ? Kdestop doesn't crash. Do you have any idea ?
Comment 10 EJ Finneran 2006-05-17 18:23:00 UTC 
This bug has also been reported in Kubuntu Dapper.

Comment 11 Dik Takken 2006-05-20 21:18:03 UTC 
I have exactly the same problem here on Gentoo Linux, KDE 3.5.2. I am almost certain that this problem did not occur on KDE 3.5.0.

What happens is that sometimes when I press the right mouse button on a KDesktop icon, KDesktop freezes. Whenever I call the RMB menu in any Konqueror window, this Konqueror window will freeze again. Only when I kill KDesktop, the Konqueror windows show the RMB menus and are alive again. Seems like the RMB menu calls KDesktop and blocks until it responds or dies.

Here is the backtrace, created when KDesktop was frozen:

According to equery, libkuickplugin.so belongs to a konqueror plugin. Maybe this is a plugin that adds entries to the RMB menu?

Comment 14 Daniel Frein 2006-06-03 11:00:41 UTC 
as Harm van Bakel discovered, kopete seems responsible for the freezing of kdesktop: https://launchpad.net/distros/ubuntu/+source/kdebase/+bug/43065

after the desktop freezes, a "killall kopete" brings kdesktop back to its normal state. after killing kopete, the following messages are appearing in ~/.xsession-errors:
DCOP aborting call from 'kdesktop' to 'kopete'
DCOP aborting while waiting for answer from 'kdesktop'
DCOPServer::DCOPReply for unknown connection.

In contrast to the reports above, I was never able to generate backtraces of kdesktop during its freezed state.

Comment 16 Dik Takken 2006-06-03 13:00:23 UTC 
You are right! I did not have Kopete loaded for two weeks now, and the freezes were gone. I just loaded Kopete again, and after right-clicking KDesktop icons about 20 times, KDesktop froze again. Killing Kopete unlocks the desktop again.

I do not get any relevant messages in my .xsession-errors, because Kopete has no debug info on my setup.

Yes, it's true !!! At last, we have found the origin of this problem.

It's necessary to change this bug's category, it's a kopete bug, not a kdesktop bug.

Could someone change the category ?
Comment 18 marseillai 2006-06-03 13:21:14 UTC 
bug is already report here http://bugs.kde.org/show_bug.cgi?id=127749 as a kopete bug

I think this is enough evidence to assign this bug to Kopete.

Maybe it should have a higher severity settings as well, as if freezes a large part of the KDE desktop.

Comment 20 FiNeX 2009-01-02 20:32:28 UTC 
Bug closed. Kdesktop is no more mantained.
