Comment 1 Oliver Putz 2008-11-02 12:13:11 UTC 
Hi, thanks for your bugreport. Could you perhaps describe what you were doing when the crash happened? (It looks like the crash occurred in KNewStuff) Can you perhaps even reliably reproduce it? If so, how?

Plasma crash backtrace

Plasma crashed after adding the "file watcher" plasmoid, and choosing the file to watch.

Crasch when trying to change plasma settings

I used the tool to change settings for my desktop (in swedish: "Anpassa skrivbordet") and changed the number of desktops from 4 to 2. When I pushed the button to carry out the changes, plasma crashed and all my previous settings disappeared except that I now have default settings on everything but the number of desktops. I now have 2. All other settings disappeared. These were additions made during the same login session.

Crasch when trying to change plasma settings

I now remember thet there were applications running on desktop 3 when I changed the settings
Comment 6 Oliver Putz 2008-11-12 11:31:10 UTC 
@Serafim: The backtrace you attached seems unrelated to the crash described in this bugreport. If you can reproduce the crah, can you please have a look at http://techbase.kde.org/Development/Tutorials/Debugging/How_to_create_useful_crash_reports, install the debugging symbols for your distribution and create a new bugreport for the crash? (Its also useful to have the debugging packages installed just in case that you stuble across some "random crash") Regrettably here decreasing the number of desktops works.
Comment 7 Oliver Putz 2008-11-12 11:38:49 UTC 
@Guillermo: Regrettaby I cannot reproduce your crash here. Furthermore your problem seems different from the one being dealt with in this bugreport. If this crash happens frequently to you I'd suggest that you too have a look at http://techbase.kde.org/Development/Tutorials/Debugging/How_to_create_useful_crash_reports, install the debugging packages for your distribution and create a new bugreport with a more verbose backtrace. Thanks!
Comment 8 Oliver Putz 2008-11-12 11:41:54 UTC 
@Guillermo once more: Actually, I guess what you experienced was in fact the same problem already reported in bug #174113.

@Oliver: I installed the debugging packages, but I haven't been able to reproduce the error.

Comment 15 Teemu Kauhanen 2008-12-15 20:06:01 UTC 
Fix found here https://bugs.launchpad.net/ubuntu/+source/kdebase-workspace/+bug/258861

When dragging url from browser to desktop OR desktop widget? it generates "script?" on ~/.kde/share/config/plasma-appletsrc and that "script?" causes the crash

I hope dragging wont generate the script, because "normal" users wont figure this out.
Comment 16 Marty Felker 2008-12-24 06:00:42 UTC 
Created attachment 29598 [details]
Attachment saved while KDE 4 produced Segfault 11

After installing last update using apt-get update/dist-upgrade (2 library files (forget which) I logged in using my username and password and got this Segfault but only on the last step (KDE desktop icon).  Before the upgrade desktop was fine and I had a Kget session  running.
which I stopped 4 .torrents and then logged in again (from my default Gnome).  As I type I'm using Konqueror to save the attachment <plasma.kcrash.  Since KDE 4.0 the Plasma  was the most unstable feature in KDE4 and apparently has yet to be debuuged,

I had installed debug package containing libkdeinit4_plasma, but it didn't show full trace. And there is no debug package for libglib-2.0.so.0.
Comment 18 Ashley 2009-01-08 18:18:15 UTC 
I moved a panel, deleted a panel, and have cairo-dock running with compiz as the window manager. It crashed after i deleted the panel, bringing the panel back and moving the other panel to where it was originally.

Comment 20 Dario Andres 2009-01-24 15:05:40 UTC 
The original crash is bug 167473 (now fixed)

There are a lot of different and completely unrelated crashes here.

To all the crash reporters of this bug:
If you can still reproduce your crashes using a recent KDE version (4.1.4/ 4.1.96 / 4.2.0), please, before creating a new report, check the backtraces inside a possible "duplicate". If you look at your backtraces you will notice they are a LOT different to the original reported here. Try to not guide yourselfs by the report title (as this may lead to a lot of confusion and report mixing)

BTW the Mandriva crash (comment 13) is due a bug in the Mandriva launcher, you should report that crash to Mandriva team as it isn't KDE fault
Thanks to all.
