Version: (using KDE 4.2.2) OS: Linux Installed from: Fedora RPMs i hit ctrl-esc to bring up the System monitor, and then i search for "mplayer" to terminate a mplayer process that i want to. and suddenly it crash and kcrash made the follow backtrace : ------------------ Application: Run Command Interface (krunner), signal SIGSEGV [Current thread is 1 (Thread 0xb7ed29d0 (LWP 11612))] Thread 1 (Thread 0xb7ed29d0 (LWP 11612)): [KCrash Handler] #6 0x0703efd4 in QSortFilterProxyModel::parent(QModelIndex const&) const () from /usr/lib/libQtGui.so.4 #7 0x06ff37cb in QTreeView::drawRow(QPainter*, QStyleOptionViewItem const&, QModelIndex const&) const () from /usr/lib/libQtGui.so.4 #8 0x06ffa76c in QTreeView::drawTree(QPainter*, QRegion const&) const () from /usr/lib/libQtGui.so.4 #9 0x06ffb1bd in QTreeView::paintEvent(QPaintEvent*) () from /usr/lib/libQtGui.so.4 #10 0x06a8b252 in QWidget::event(QEvent*) () from /usr/lib/libQtGui.so.4 #11 0x06e6ac93 in QFrame::event(QEvent*) () from /usr/lib/libQtGui.so.4 #12 0x06f0acb4 in QAbstractScrollArea::viewportEvent(QEvent*) () from /usr/lib/libQtGui.so.4 #13 0x06fbeeb7 in QAbstractItemView::viewportEvent(QEvent*) () from /usr/lib/libQtGui.so.4 #14 0x06ff98de in QTreeView::viewportEvent(QEvent*) () from /usr/lib/libQtGui.so.4 #15 0x06f0d2f5 in ??

What is your Qt version ? Thanks
it is: qt-4.5.0-14.fc11.i586 and qt3 if you are interested: qt3-3.3.8b-25.fc11.i586

I have once again produced this bug i think, but still not yet a confirmed way to reproduce it. what i was doing was start a new search while krunner is trying to terminate a process which i told it to. Here is the backtrace for this time: ---------------------- Application: Run Command Interface (krunner), signal SIGSEGV 0x0000003b772a5151 in nanosleep () from /lib64/libc.so.6 [Current thread is 1 (Thread 0x7ffe83de8860 (LWP 8990))] Thread 1 (Thread 0x7ffe83de8860 (LWP 8990)): [KCrash Handler] #5 0x0000003b84d1d88f in ??

Yea, starting a new search while terminating a process seems to be able to reproduce the crash at will.
