Application: dolphin (1.6.1) KDE Platform Version: 4.6.3 (4.6.3) Qt Version: 4.7.2 Operating System: Linux 2.6.38.7-30.fc15.x86_64 x86_64 Distribution: "Fedora release 15 (Lovelock)" -- Information about the crash: The system is F15 x86_64. I closed the Dolphin window after copying some files to an sd card. Copying was very slow with dstat showing bursts of writes and long pauses. The whole desktop was unresponsive during the pauses. Not sure if it is related to the crash. The crash can be reproduced some of the time. -- Backtrace: Application: Dolphin (dolphin), signal: Segmentation fault 82 T_PSEUDO (SYSCALL_SYMBOL, SYSCALL_NAME, SYSCALL_NARGS) [KCrash Handler] #6 0x0000003d36a9a382 in QX11PixmapData::release (this=0x2abb9f0) at image/qpixmap_x11.cpp:1249 #7 0x0000003d36a9a4a4 in QX11PixmapData::~QX11PixmapData (this=0x2abb9f0, __in_chrg=<optimized out>) at image/qpixmap_x11.cpp:1244 #8 0x0000003d36a9a4f9 in QX11PixmapData::~QX11PixmapData (this=0x2abb9f0, __in_chrg=<optimized out>) at image/qpixmap_x11.cpp:1245 #9 0x0000003d36a87ab9 in ~QExplicitlySharedDataPointer (this=0x2ad58f0, __in_chrg=<optimized out>) at ../../src/corelib/tools/qshareddata.h:161 #10 ~QExplicitlySharedDataPointer (this=0x2ad58f0, __in_chrg=<optimized out>) at image/qpixmap.cpp:321 #11 QPixmap::~QPixmap (this=0x2ad58e0, __in_chrg=<optimized out>) at image/qpixmap.cpp:321 #12 0x00007fc7d40b3357 in QVector<QPixmap>::free (this=<optimized out>, x=0x2ad58d0) at /usr/include/QtCore/qvector.h:438 #13 0x00007fc7d40b33f2 in ~QVector (this=0x2ad0aa8, __in_chrg=<optimized out>) at /usr/include/QtCore/qvector.h:119 #14 ~TileSet (this=0x2ad0aa0, __in_chrg=<optimized out>) at /usr/src/debug/kdebase-workspace-4.6.3/libs/oxygen/oxygentileset.h:75 #15 Oxygen::TileSet::~TileSet (this=0x2ad0aa0, __in_chrg=<optimized out>) at /usr/src/debug/kdebase-workspace-4.6.3/libs/oxygen/oxygentileset.h:75 #16 0x00007fc7d435cc87 in QCache<unsigned long long, Oxygen::TileSet>::clear (this=0x1f34e40) at /usr/include/QtCore/qcache.h:139 #17 0x00007fc7d435e95e in ~QCache (this=0x1f34e40, __in_chrg=<optimized out>) at /usr/include/QtCore/qcache.h:103 #18 ~BaseCache (this=0x1f34e40, __in_chrg=<optimized out>) at /usr/src/debug/kdebase-workspace-4.6.3/libs/oxygen/oxygenhelper.h:59 #19 Oxygen::StyleHelper::~StyleHelper (this=0x1f349c0, __in_chrg=<optimized out>) at /usr/src/debug/kdebase-workspace-4.6.3/kstyles/oxygen/oxygenstylehelper.h:47 #20 0x00007fc7d435eec9 in Oxygen::StyleHelper::~StyleHelper (this=0x1f349c0, __in_chrg=<optimized out>) at /usr/src/debug/kdebase-workspace-4.6.3/kstyles/oxygen/oxygenstylehelper.h:47 #21 0x00007fc7d432978d in Oxygen::Style::~Style (this=0x1f2f970, __in_chrg=<optimized out>) at /usr/src/debug/kdebase-workspace-4.6.3/kstyles/oxygen/oxygenstyle.cpp:188 #22 0x00007fc7d43297d9 in Oxygen::Style::~Style (this=0x1f2f970, __in_chrg=<optimized out>) at /usr/src/debug/kdebase-workspace-4.6.3/kstyles/oxygen/oxygenstyle.cpp:188 #23 0x0000003d369c0e27 in QApplication::~QApplication (this=0x7fff67c86780, __in_chrg=<optimized out>) at kernel/qapplication.cpp:1155 #24 0x0000003d3a4433cf in kdemain (argc=6, argv=0x7fff67c86ca8) at /usr/src/debug/kdebase-4.6.3/dolphin/src/main.cpp:82 #25 0x000000342fc2139d in __libc_start_main (main=0x400790 <main(int, char**)>, argc=6, ubp_av=0x7fff67c86ca8, init=<optimized out>, fini=<optimized out>, rtld_fini=<optimized out>, stack_end=0x7fff67c86c98) at libc-start.c:226 #26 0x00000000004007c1 in _start () Possible duplicates by query: bug 269246, bug 268923, bug 247041. Reported using DrKonqi
The crash happens deep down ~QExplicitlySharedDataPointer. Which for well formed Shared pointers should not happen (there can't be double deletion of these things inside downstream code). So I believe this is Qt bug ...
