Confirmed for me, 4.6.5 worked fine, 4.7.0 crashes plasma-desktop when grid-layout is activated. Relevant backtrace: #6 0x00007f5cf23322ab in QString::length (this=0x13cc410) at ../../include/QtCore/../../src/corelib/tools/qstring.h:700 #7 0x00007f5cf2368f11 in QString::operator< (this=0x7fff934a2d10, other=...) at tools/qstring.cpp:2204 #8 0x00007f5ce2da8fcf in GroupInfo::operator< (this=0x13cc560, gi=...) at /usr/tmp/portage/kde-base/kdeplasma-addons-4.7.0/work/kdeplasma-addons-4.7.0/containments/groupingdesktop/lib/groupinfo.cpp:97 #9 0x00007f5ce2daa082 in qMapLessThanKey<GroupInfo> (key1=..., key2=...) at /usr/include/qt4/QtCore/qmap.h:107 #10 0x00007f5ce2dbf3fa in QMap<GroupInfo, AbstractGroup* (*)(QGraphicsItem*)>::mutableFindNode (this=0x12d05c0, aupdate=0x7fff934a2dd0, akey=...) at /usr/include/qt4/QtCore/qmap.h:782 #11 0x00007f5ce2dbf155 in QMap<GroupInfo, AbstractGroup* (*)(QGraphicsItem*)>::insert (this=0x12d05c0, akey=..., avalue=@0x7fff934a2e78) at /usr/include/qt4/QtCore/qmap.h:562 #12 0x00007f5ce2dc9c4d in GroupFactory::registerGroup<FlowGroup> (this=0x12d05c0) at /usr/tmp/portage/kde-base/kdeplasma-addons-4.7.0/work/kdeplasma-addons-4.7.0/containments/groupingdesktop/lib/groupfactory_p.h:47 #13 0x00007f5ce2dc9b3e in __static_initialization_and_destruction_0 (__initialize_p=1, __priority=65535) at /usr/tmp/portage/kde-base/kdeplasma-addons-4.7.0/work/kdeplasma-addons-4.7.0/containments/groupingdesktop/lib/groups/flowgroup.cpp:37 #14 0x00007f5ce2dc9b59 in global constructors keyed to flowgroup.cpp(void) () at /usr/tmp/portage/kde-base/kdeplasma-addons-4.7.0/work/kdeplasma-addons-4.7.0_build/containments/groupingdesktop/lib/flowgroup.moc:86 #15 0x00007f5ce2dd4ef6 in ?? () from /usr/lib64/libplasma_groupingcontainment.so.4 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. *** Bug 278725 has been marked as a duplicate of this bug. *** *** Bug 278797 has been marked as a duplicate of this bug. *** 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.

plasma-desktop (0.4) on KDE Platform 4.7.00 (4.7.0) using Qt 4.7.2
- What I was doing when the application crashed:
1. Installed kdeplasma-addons/project-neon-kdeplasma-addons
2. Right click desktop >> Desktop Settings
3. Select Grid Desktop from the layout option.
4. Plasma crashes.

I can confirm this on Gentoo, since upgrading to KDE 4.7.0 plasma-desktop crashes on startup.
