I've seen "tooltip" in the backtrace so I've tried to play with it just a litlle and found this: one of the commics (PhD Comics) has tooltip ( "Tales from the road to...." ) other comics does not show tooltip. If I switch comic fast so tooltip does not show up, everything is ok If I switch slowly when switching from comic that has no tooltip, everything is ok If I switch comic when tooltip is shown, it crashes always So there really is some problem with tooltip
Created attachment 52294 [details] New crash information added by DrKonqi plasma-desktop (0.3) on KDE Platform 4.5.2 (KDE 4.5.2) using Qt 4.6.3 I can confirm the same behaviour - problem with tooltip. When I switch comixes and the tooltip is shown, the application crashes. I'm using XKCD (with tooltip), Garfield and Dilbert, so when I switch from XKCD, I see the crash. -- Backtrace (Reduced): #7 0xb4e7b805 in Plasma::ToolTip::setContent (this=0x0, tipper=0xa3b4f90, data=...) at /mnt/data/tmp/portage/kde-base/kdelibs-4.5.2/work/kdelibs-4.5.2/plasma/private/tooltip.cpp:300 #8 0xb4eb4ec1 in Plasma::ToolTipManager::setContent (this=0xa110a20, widget=0xa3b4f90, data=...) at /mnt/data/tmp/portage/kde-base/kdelibs-4.5.2/work/kdelibs-4.5.2/plasma/tooltipmanager.cpp:239 #9 0xab2c161f in ComicApplet::dataUpdated (this=0xa3be920, data=...) at /mnt/data/tmp/portage/kde-base/kdeplasma-addons-4.5.1/work/kdeplasma-addons-4.5.1/applets/comic/comic.cpp:430 #10 0xab2c631d in ComicApplet::qt_metacall (this=0xa3be920, _c=QMetaObject::InvokeMetaMethod, _id=0, _a=0xbffb5414) at /mnt/data/tmp/portage/kde-base/kdeplasma-addons-4.5.1/work/kdeplasma-addons-4.5.1_build/applets/comic/comic.moc:107 [...] [...] #13 0xb4e097d8 in Plasma::DataContainer::dataUpdated (this=0xa6e1668, _t1=..., _t2=...) at /mnt/data/tmp/portage/kde-base/kdelibs-4.5.2/work/kdelibs-4.5.2_build/plasma/datacontainer.moc:101
I can also confirm that behaviour and it never happened to me before, I think it might have been introduced in 4.5.2. The problem are the following lines: Plasma::ToolTipContent toolTipData; if ( !mAdditionalText.isEmpty() ) { toolTipData = Plasma::ToolTipContent( mAdditionalText, QString() ); toolTipData.setAutohide( false ); } Plasma::ToolTipManager::self()->setContent( mMainWidget, toolTipData ); So setting an empty Plasma::ToolTipContent when there is already something displayed crashes it _always_.
