Version: Version 4.1.1 (KDE 4.1.0 (4.1 >= 20080722)) (using KDE 4.1.0) Compiler: gcc OS: Linux Installed from: Unlisted Binary Package Using KDE 4.1.1 (KDE 4.1.0 (4.1 >= 20080722)) (KDEmod) in ArchLinux i686 Steps to reproduce: - Open Konqueror - Load some site (example url : http://www.clarin.com ) Before the site is loaded (inmediatly after you press Return) press F7 (Toggle Caret Mode) two or three times. Konqueror crashes. This may also happen with another sites. This bug is also reproducible using KDE4.2 svn (kdelibs rev.851858 and kdebase rev.851866) Here is the backtrace: Aplicación: Konqueror (konqueror), señal SIGSEGV [Thread debugging using libthread_db enabled] [New Thread 0xb6339700 (LWP 4970)] [KCrash handler] #6 setCaretInvisibleIfNeeded (part=0x8409028) at /home/jan/Source/packages/kde41/work/kdelibs/src/kdelibs-4.1.0/khtml/khtml_part.cpp:2701 #7 0xb450008a in KHTMLPart::setCaretMode (this=0x8409028, enable=false) at /home/jan/Source/packages/kde41/work/kdelibs/src/kdelibs-4.1.0/khtml/khtml_part.cpp:2717 #8 0xb4500265 in KHTMLPart::slotToggleCaretMode (this=0x8409028) at /home/jan/Source/packages/kde41/work/kdelibs/src/kdelibs-4.1.0/khtml/khtml_part.cpp:7339 #9 0xb4511b80 in KHTMLPart::qt_metacall (this=0x8409028, _c=QMetaObject::InvokeMetaMethod, _id=83, _a=0xbf998a7c) at /home/jan/Source/packages/kde41/work/kdelibs/src/build/khtml/khtml_part.moc:328 #10 0xb748a8d7 in QMetaObject::activate () from /usr/lib/libQtCore.so.4 #11 0xb748abb9 in QMetaObject::activate () from /usr/lib/libQtCore.so.4 #12 0xb6a2bfe2 in QAction::triggered () from /usr/lib/libQtGui.so.4 #13 0xb6a2c868 in QAction::activate () from /usr/lib/libQtGui.so.4 #14 0xb6a2efeb in QAction::event () from /usr/lib/libQtGui.so.4 #15 0xb6a80320 in QWidgetAction::event () from /usr/lib/libQtGui.so.4 #16 0xb6a30f13 in QApplicationPrivate::notify_helper () from /usr/lib/libQtGui.so.4 #17 0xb6a37a1c in QApplication::notify () from /usr/lib/libQtGui.so.4 #18 0xb7a2aedc in KApplication::notify (this=0xbf999d94, receiver=0x878fd38, event=0xbf998e54) at /home/jan/Source/packages/kde41/work/kdelibs/src/kdelibs-4.1.0/kdeui/kernel/kapplication.cpp:311 #19 0xb747a30c in QCoreApplication::notifyInternal () from /usr/lib/libQtCore.so.4 #20 0xb6a619de in ??

@Jaime: the patch was not "approved" by the devs (I asked at #khtml directly); as it was just a dirty workaround to a bad situation (that should not happen).
Created attachment 63804 [details] New crash information added by DrKonqi konqueror (4.7.1 (4.7.1)) on KDE Platform 4.7.1 (4.7.1) using Qt 4.7.4 - What I was doing when the application crashed: 1. Start op Konqueror. Konqueror starts withe its default 'Be free' page. 2. Press the following keys: F2 F3 F4 F5 F6 F7 F8 F2 F3 F4 F5 F6 F7 3. Pressing F7 the second time crashes Konqueror. -- Backtrace (Reduced): #6 0x00007fcc685677ba in setCaretInvisibleIfNeeded (part=0xab9c40) at /usr/src/debug/kdelibs-4.7.1/khtml/khtml_part.cpp:2846 #7 0x00007fcc6858387a in setCaretMode (enable=false, this=0xab9c40) at /usr/src/debug/kdelibs-4.7.1/khtml/khtml_part.cpp:2862 #8 KHTMLPart::setCaretMode (this=0xab9c40, enable=false) at /usr/src/debug/kdelibs-4.7.1/khtml/khtml_part.cpp:2850 #9 0x00007fcc68593a74 in KHTMLPart::qt_metacall (this=0xab9c40, _c=QMetaObject::InvokeMetaMethod, _id=86, _a=0x7ffff7b320e0) at /usr/src/debug/kdelibs-4.7.1/build/khtml/khtml_part.moc:345 [...] #11 0x00007fcc7f0b45d2 in QAction::triggered (this=<optimized out>, _t1=false) at .moc/release-shared/moc_qaction.cpp:263

Dear user, KHTML (and KJS) was a long time more or less unmaintained and got removed in KF6. Please migrate to use a QWebEngine based HTML component. We will do no further fixes or improvements to the KF5 branches of these components beside important security fixes. For security issues, please see: https://kde.org/info/security/ Sorry that we did not fix this issue during the life-time of KHTML. Greetings Christoph Cullmann
