The KDE Crash Handler prepared me a nice report that it is now failing to upload (you must log in...). Here it is: Application: dolphin (4.13.3) KDE Platform Version: 4.13.3 Qt Version: 4.8.6 Operating System: Linux 3.16.0-31-generic x86_64 Distribution: Ubuntu 14.04.2 LTS -- Information about the crash: - What I was doing when the application crashed: Dragging a file from one window to another. - Unusual behavior I noticed: Approximately 1/4th of the time I do this, the source window will show an undesired small pop up: it seems to be a listing of directories, not sure. This is in addition to the pop-up on the destination window asking if I wanted to move or copy. It may have to do with the exact path my mouse takes as I move between windows. 3/4ths of the time this happens, I can close the pop-up by clicking elsewhere in the window that showed it. The other 1/4th of the time, that click results in a crash. The crash can be reproduced sometimes. -- Backtrace: Application: Dolphin (dolphin), signal: Segmentation fault Using host libthread_db library "/lib/x86_64-linux-gnu/libthread_db.so.1".

Open two dolphin windows. 2. Drag files repeatedly between the windows. It may be relevant that the windows were stacked vertically, not horizontally. 3. Dismiss annoying pop-ups that happen randomly as this is done. Actual Results: Crash, and crash report tool failure. Expected Results: Uh, not crash? Avoiding the dumb pop-up would be nice too. I'm set up for double-click to open files, not sure if that's relevant.
Does this crash also happen when you uninstall the NVIDIA binary driver and use the nouveau driver?

Yes, this is intentional. This menu makes it easy to move files to subdirectories of directories which are shown in the location bar. And this is not a Dolphin-specific feature, by the way - you'll get the same behaviour in the KDE file dialog and possibly in more places. I could not reproduce the crash, I just got some warnings from Valgrind when I tried to (they were caused by invalid reads/writes in QDrag::exec()). It might be helpful if you could try to get a Valgrind log of the crash, see https://community.kde.org/Dolphin/FAQ/Crashes . Such a log might tell us what the cause of the crash is, and provide information about how to fix it. Or maybe it would help to know if the location of the moved file in the directory tree is important in order to reproduce the crash. Maybe you could attach a screenshot of the situation before the drag&drop which can lead to a crash, and tell us which file you try to move? Thanks for your help!

I can see this potentially being useful, but I would expect to have to hover over the arrow for maybe 500ms before the pop-up happens, rather than incidentally passing over it. Also, if the pop-up were to close itself after maybe a second of the mouse not being over the arrow or the pop-up, it would be less intrusive than having to click to dismiss it. But, this is somewhat off-topic. > I could not reproduce the crash, I just got some warnings from Valgrind when > I tried to (they were caused by invalid reads/writes in QDrag::exec()).

Such a log might tell us > what the cause of the crash is, and provide information about how to fix it. I was also unable to reproduce while running under valgrind. Perhaps the timing is too different? I did get one valgrind complaint in the output, probably the same that you got: ==14552== Invalid write of size 4 ==14552== at 0x806FE3A: QDrag::exec(QFlags<Qt::DropAction>, Qt::DropAction) (in /usr/lib/x86_64-linux-gnu/libQtGui.so.4.8.6) ==14552== by 0x5E831E1: KItemListController::startDragging() (kitemlistcontroller.cpp:1176) ==14552== by 0x5E83307: KItemListController::mouseMoveEvent(QGraphicsSceneMouseEvent*, QTransform const&) (kitemlistcontroller.cpp:687) ==14552== by 0x5E7FBAA: KItemListController::processEvent(QEvent*, QTransform const&) (kitemlistcontroller.cpp:1032) ==14552== by 0x5E907A1: KItemListView::event(QEvent*) (kitemlistview.cpp:908) ==14552== by 0x805EE2B: QApplicationPrivate::notify_helper(QObject*, QEvent*) (in /usr/lib/x86_64-linux-gnu/libQtGui.so.4.8.6) ==14552== by 0x806549F: QApplication::notify(QObject*, QEvent*) (in /usr/lib/x86_64-linux-gnu/libQtGui.so.4.8.6) ==14552== by 0x7A6FD19: KApplication::notify(QObject*, QEvent*) (kapplication.cpp:311) ==14552== by 0x91864DC: QCoreApplication::notifyInternal(QObject*, QEvent*) (in /usr/lib/x86_64-linux-gnu/libQtCore.so.4.8.6) ==14552== by 0x862F0F0: QGraphicsScenePrivate::sendEvent(QGraphicsItem*, QEvent*) (in /usr/lib/x86_64-linux-gnu/libQtGui.so.4.8.6) ==14552== by 0x862F5AE: QGraphicsScenePrivate::sendMouseEvent(QGraphicsSceneMouseEvent*) (in /usr/lib/x86_64-linux-gnu/libQtGui.so.4.8.6) ==14552== by 0x8638175: QGraphicsScene::mouseMoveEvent(QGraphicsSceneMouseEvent*) (in /usr/lib/x86_64-linux-gnu/libQtGui.so.4.8.6) ==14552== Address 0x1d2ccc54 is 196 bytes inside a block of size 216 free'd ==14552== at 0x4C2C2BC: operator delete(void*) (in /usr/lib/valgrind/vgpreload_memcheck-amd64-linux.so) ==14552== by 0x919F734: QObject::~QObject() (in /usr/lib/x86_64-linux-gnu/libQtCore.so.4.8.6) ==14552== by 0x806FBF8: QDrag::~QDrag() (in /usr/lib/x86_64-linux-gnu/libQtGui.so.4.8.6) ==14552== by 0x919EC57: QObject::event(QEvent*) (in /usr/lib/x86_64-linux-gnu/libQtCore.so.4.8.6) ==14552== by 0x805EE2B: QApplicationPrivate::notify_helper(QObject*, QEvent*) (in /usr/lib/x86_64-linux-gnu/libQtGui.so.4.8.6) ==14552== by 0x806549F: QApplication::notify(QObject*, QEvent*) (in /usr/lib/x86_64-linux-gnu/libQtGui.so.4.8.6) ==14552== by 0x7A6FD19: KApplication::notify(QObject*, QEvent*) (kapplication.cpp:311) ==14552== by 0x91864DC: QCoreApplication::notifyInternal(QObject*, QEvent*) (in /usr/lib/x86_64-linux-gnu/libQtCore.so.4.8.6) ==14552== by 0x9189B3C: QCoreApplicationPrivate::sendPostedEvents(QObject*, int, QThreadData*) (in /usr/lib/x86_64-linux-gnu/libQtCore.so.4.8.6) ==14552== by 0x91B3F82: postEventSourceDispatch(_GSource*, int (*)(void*), void*) (in /usr/lib/x86_64-linux-gnu/libQtCore.so.4.8.6) ==14552== by 0xE1CCE03: g_main_context_dispatch (in /lib/x86_64-linux-gnu/libglib-2.0.so.0.4002.0) ==14552== by 0xE1CD047: ???

Here's the command I ran to reproduce: $ mkdir tmp1 tmp2; for i in `seq 0 1000`; do touch tmp1/$i; done; dolphin tmp? This opens two tabs in dolphin. I right-clicked the second, and detached the tab. I then repeatedly dragged files from tmp1/ to tmp2/, making sure to pass over the arrow each time. The crash happened on the third file moved. I tried this for a while in valgrind, and made it up to 40 before giving up.

Thanks for the detailed information! Unfortunately, I'm still unable to reproduce the problem.

Can somebody still reproduce this bug with Dolphin 17.12.3 or 18.04?
(In reply to Julian Schraner from comment #10) > Can somebody still reproduce this bug with Dolphin 17.12.3 or 18.04? I don't have easy access to those versions yet, but I am unable to reproduce on 15.12.3 on 16.04.
Okay, I'll close this report in this case. If the bug does reappear in a newer version of Dolphin, then please reopen the report. Thanks!
