Crash backtrace
I'd say the problem here is that konqueror removes things from kpdf foot too late in the process of "destroying" the html page to load the other and kpdf as problems with that, what do you konq guys think? Valgrindizin seems the "ui" of kpdf got destroyed before than the part itself ==10759== Invalid read of size 8 ==10759== at 0x1A194F92: KPDFDocument::closeDocument() (document.cpp:252) ==10759== by 0x1A19523C: KPDFDocument::~KPDFDocument() (document.cpp:127) ==10759== by 0x1A09886F: KPDF::Part::~Part() (part.cpp:294) ==10759== by 0x1205E6BA: KParts::Part::slotWidgetDestroyed() (in /home/kde35/instalado/lib/libkparts.so.2.1.0) ==10759== by 0x1205E85C: KParts::Part::qt_invoke(int, QUObject*) (in /home/kde35/instalado/lib/libkparts.so.2.1.0) ==10759== by 0x1205EAD9: KParts::ReadOnlyPart::qt_invoke(int, QUObject*) (in /home/kde35/instalado/lib/libkparts.so.2.1.0) ==10759== by 0x1A09D752: KPDF::Part::qt_invoke(int, QUObject*) (part.moc:214) ==10759== by 0x13E36878: QObject::activate_signal(QConnectionList*, QUObject*) (in /usr/lib/libqt-mt.so.3.3.4) ==10759== by 0x13E372DF: QObject::activate_signal(int) (in /usr/lib/libqt-mt.so.3.3.4) ==10759== by 0x14172315: QObject::destroyed() (in /usr/lib/libqt-mt.so.3.3.4) ==10759== by 0x13E352CC: QObject::~QObject() (in /usr/lib/libqt-mt.so.3.3.4) ==10759== by 0x13E6D04D: QWidget::~QWidget() (in /usr/lib/libqt-mt.so.3.3.4) ==10759== Address 0x19933B10 is 248 bytes inside a block of size 264 free'd ==10759== at 0x11B1DCCC: operator delete(void*) (vg_replace_malloc.c:246) ==10759== by 0x1A1A8EB5: PageView::~PageView() (pageview.cpp:175) ==10759== by 0x13E6CF87: QWidget::~QWidget() (in /usr/lib/libqt-mt.so.3.3.4) ==10759== by 0x11F053D2: QFrame::~QFrame() (qframe.h:48) ==10759== by 0x13F6C888: QSplitter::~QSplitter() (in /usr/lib/libqt-mt.so.3.3.4) ==10759== by 0x13E338F4: QObject::event(QEvent*) (in /usr/lib/libqt-mt.so.3.3.4) ==10759== by 0x13E6E36A: QWidget::event(QEvent*) (in /usr/lib/libqt-mt.so.3.3.4) ==10759== by 0x13F6DC4E: QSplitter::event(QEvent*) (in /usr/lib/libqt-mt.so.3.3.4) ==10759== by 0x13DD11E3: QApplication::internalNotify(QObject*, QEvent*) (in /usr/lib/libqt-mt.so.3.3.4) ==10759== by 0x13DD1F3F: QApplication::notify(QObject*, QEvent*) (in /usr/lib/libqt-mt.so.3.3.4) ==10759== by 0x1309E9E0: KApplication::notify(QObject*, QEvent*) (kapplication.cpp:550) ==10759== by 0x11CC698B: QApplication::sendEvent(QObject*, QEvent*) (qapplication.h:491) *** Bug 122200 has been marked as a duplicate of this bug. *** SVN commit 510876 by aacid: Reoder some deletes, add some removeObserver and use some magic QGuardPtr so that when embedded on konqueror and changing page it does crash, i still think that konqueror should not delete kpart created widgets behind its back, but probably it's easier to change kpdf than all the other code.
