Application: plasma-desktop (0.3) KDE Platform Version: 4.4.2 (KDE 4.4.2) Qt Version: 4.6.2 Operating System: Linux 2.6.32-22-generic x86_64 Distribution: Ubuntu 10.04 LTS -- Information about the crash: hello! maybe I just didnt find the duplicate for this bug... Well I removed the only one panel I had on the desktop. KDE crashed. My real problem is, that when I try to add again a panel, I can only add the widgets, but not some very important "default" things, as the small icon-assembly - I mean the time, date, notifications, (the space where also skype appears) and the WLAN-icon. So I can't go online any more, since kubuntu doesn't see my network cable at all, I can only connect through wlan.(maybe I can connect throught the terminal, but I only know how to scan the available networks... :/) so I created a new user account, and I had the panel with all the "small" icons at. from the new user I tryed to remove the panel again. It happened again - kde crash, no wlan icon on the new panel. How can I put it back? Now Im still connected to the internet, but I don't have any idea how to do it the next time when I log in. If I dont create another user account, of course... Because also network manager doesn't open any more at all! also with sudo from the terminal - it says it is running. When I "kill" it, I also can't open it again :( This is maybe because the 1st crash happened while kubuntu was updating itself... I know now it's really stupid to remove the panel while linux is making the updates... HELP ME! Ana The crash can be reproduced some of the time. -- Backtrace: Application: Plasma Workspace (kdeinit4), signal: Segmentation fault [Current thread is 1 (Thread 0x7f14d4fac760 (LWP 1556))] Thread 3 (Thread 0x7f14b7c6c710 (LWP 1558)): #0 pthread_cond_wait@@GLIBC_2.3.2 () at ../nptl/sysdeps/unix/sysv/linux/x86_64/pthread_cond_wait.S:162 #1 0x00007f14c804c2a6 in QTWTF::TCMalloc_PageHeap::scavengerThread (this=0x7f14c832a220) at ../3rdparty/javascriptcore/JavaScriptCore/wtf/FastMalloc.cpp:2304 #2 0x00007f14c804c2e9 in QTWTF::TCMalloc_PageHeap::runScavengerThread (context=0x7f14c83382ec) at ../3rdparty/javascriptcore/JavaScriptCore/wtf/FastMalloc.cpp:1438 #3 0x00007f14d31ed9ca in start_thread (arg=<value optimized out>) at pthread_create.c:300 #4 0x00007f14d1fa06cd in clone () at ../sysdeps/unix/sysv/linux/x86_64/clone.S:112 #5 0x0000000000000000 in ??

> "default" things, as the small icon-assembly - I mean the time, date, > notifications, (the space where also skype appears) > and the WLAN-icon. time/date is not in the system tray, it's a separate widget (digital clock). as for the networking entry, right click on the system tray and select "System Tray Settings" and you can enable it in there (if kubuntu is using the networking plasmoid) or start the knetworkmanager application. in any case, use support can be had in forum.kde.org or the kubuntu forums. > How can I put it back? in 4.5, right click on the desktop -> add panel -> default panel. in 4.4, it's similar, but there is no "default panel" option. you have to add the widgets yourself. or you can stop plasma-desktop and delete ~./kde/share/config/plasma-desktop* and start plasma-desktop again. #5 0x00007f14d2ce8204 in QGraphicsItem::isPanel (this=0x2480ae0) at graphicsview/qgraphicsitem.cpp:1661 this is a but in Qt, reported and hopefully fixed in 4.7
