Version: (using Devel) Compiler: gcc (GCC) 4.2.4 (Gentoo 4.2.4 p1.0) OS: Linux Installed from: Compiled sources When I click on "Logout", "Shutdown" or "Restart" in Kickoff, I get logged out and thrown to the login screen immediately, without any confirmation, and it doesn't shutdown or restart if such an action was selected. This also happens when run in Xephyr so it's not X crashing. It started happening about two weeks ago. KDE 4.1 works fine.
What KDE version (or SVN revision) are you using? Here using: Qt: 4.4.3 + qt-copy-patches-889120 KDE: 4.2.60 (KDE 4.2.60 (KDE 4.3 >= 20090106)) kdelibs svn rev. 908156 / kdebase svn rev. 908156 on ArchLinux x86_64 - Kernel 2.6.27.10 I'm also getting a crash of ksmserver. The all session is closed immediatly after pressing Logout. No dialog appears. I also managed to get a backtrace of the crash, but I don't know if post it as it may be another bug.

Created attachment 30051 [details] backtrace I attached to ksmserver with gdb and pressed "Restart". ksmserver crashed, this is the backtrace.
Indeed, your backtrace is the same as mine, so it's the same crash
The use of Plasma::FrameSVG was introduced by svn rev. 903899. I don't know if this may be caused by a plasma/plasmasvg bug. @Aaron: sorry for bothering you, what do you think ?
It's worth noting that this does not affect everyone. Three confirmed cases for Debian's KDE 4.1.96 packages. fabo, Richih and trigger on IRC
I see the same thing in KDE 4.2 branch and it make Kopete crash. I've debugged the crash and Kopete crashes because K_GLOBAL_STATIC are destroyed immediately even before the deref() are called or anything else is done (almost like a Kopete kill)
I have discovered something: If you change your plasma theme to "Elegance" (or "Air" or maybe another non-Oxyhen), and restart the KDE session (to the change to take effect in the KSMServer logout dialog), the crash is gone and the Logout/Shutdown dialog is shown OK. Can anyone else confirm this ?
I can confirm: switching to another theme (Aya as an example), ksmserver doesn't crash and Logout/Shutdown dialog is shown OK.
I also confirm, it doesn't crash with Aya.
framesvg.cpp line 598: QPixmap right(frame->rightWidth, leftHeight); the frame->rightWidth is 0 in framesvg.cpp:598 when it crashes. The leftHeight is 8.
Now, this partly a Qt bug (patch in qt-copy, and Trolltech notified via the Task Tracker). But I've also put in a fix in libplasma (r909140).
SVN commit 909478 by alexmerry: Backport r909140: fix a crash (appearing in KSMServer) which is partly a Qt bug and partly an odd SVG. Basically, don't try creating and drawing on a pixmap if we know it will be null in advance. CCBUG: 179978 M +8 -4 framesvg.cpp WebSVN link: http://websvn.kde.org/?view=rev&revision=909478
Thanks!
PS: Wouldn't make it sense to throw an error when detecting SVG which are broken that way? It would help GFX people and result in cleaner themes.

@ Fathi Boudra Yes, changing to Aya makes it not to crash. P.S.: And Aya is a good theme :-) thanks
