Version: unspecified (using Devel) OS: Linux Today I've created a new "Grid Desktop" activity on my laptop, and plasma-desktop suddenly crashed. When plasma-desktop restarted there was a new "Desktop" activity. So I've tried to change its type by right-clicking on the desktop -> Desktop Settings -> Layout: Grid Desktop but, when I clicked "Apply", plasma-desktop crashed again. Same behavior with the "Grouping Desktop" containmnent. The backtrace I collected is the following: Application: Plasma Desktop Shell (kdeinit4), signal: Segmentation fault [Current thread is 1 (Thread 0xb5657710 (LWP 4447))] Thread 7 (Thread 0xaaf99b70 (LWP 4540)): #0 0xb7827424 in __kernel_vsyscall () #1 0xb5d56f76 in __poll (fds=0xa5d0c60, nfds=1, timeout=-1) at ../sysdeps/unix/sysv/linux/poll.c:87 #2 0xb583c84b in g_poll () from /lib/i386-linux-gnu/libglib-2.0.so.0 #3 0xb582c1af in ??

Actual Results: When applying the changes, plasma-desktop will crash immediately in both cases. Expected Results: plasma-desktop should change the containment type without any crash.
Confirmed for me, 4.6.5 worked fine, 4.7.0 crashes plasma-desktop when grid-layout is activated.

The same here. no difference between one and two screens setups.
When reverting http://quickgit.kde.org/?p=kdeplasma-addons.git&a=blobdiff&h=2106cca7e951216571f8520ef9d6f167034856c6&hp=9682500e1747f09b5ffe7f0b54eab0a8ce12a42e&hb=50e281f9610b32baef8c7891ccea70f20d44f34f&f=containments/groupingdesktop/lib/groupinfo.cpp it seems to work without crashing, but that's obviously not a fix but rather a hint of some sort of memory corruption somewhere else.
in containments/groupingdesktop/lib/groupfactory_p.h@47: template<class T> bool registerGroup() { GroupInfo gi = T::groupInfo(); m_groups.insert(gi, &createGroup<T>); return true; } The previous destructor of gi is called on every new assignment, so it's private variable d is freed now with mentioned commit. The QMap m_groups however still references gi while it is already gone and uses it to compare the keys. This seems to be fishy, but the destructor gets called and I believe it should not be called until m_groups is destroyed. Quite lucky it worked before.
Confirmed for me, as well. In the 4.7 RCs, grid desktop worked w/o crashing, and was my default layout. Upon upgrading to 4.7.0, plasma-desktop crashed every time I logged in. To work around, I edited ~/.kde4/share/config/plasma-desktop-appletsrc and changed plugin=org.kde.grid-desktop to plugin=desktop.

I confirm this bug, it didn't happen on 4.7 RC2 but happens in 4.7.0 (plasma crashes on login). And I independently found the same solution as in comment #5
I can confirmed this on openSUSE 11.4 + KDE 4.7.0. We also need a patch to fix this issue in KDE 4.7. Regards, Sebastian (openSUSE Member Freespacer)

i'm not using the grid layout, plasma-desktop crashes nevertheless. .kde4/share/config/plasma-desktop-appletsrc does not contain a line with plugin=org.kde.grid-desktop i'm using the plain old "Arbeitsfläche" (Workspace?). should i file another bug report or is it related?
