Application: dolphin (2.1) KDE Platform Version: 4.9.5 Qt Version: 4.8.4 Operating System: Linux 3.7.6-102.fc17.i686 i686 Distribution: "Fedora release 17 (Beefy Miracle)" -- Information about the crash: - What I was doing when the application crashed: I had connected a USB device (Garmin 210 Forerunner). - Unusual behavior I noticed: After I connected the USB device, I selected "open with file manager". To my surprise, it opened in Konqueror instead of Dolphin. I switched to Dolphin and opened SportsTracker (a Java application). When I closed SportsTracker (that is reading files from the above mentioned USB device), Dolphin crashed. -- Backtrace: Application: Dolphin (dolphin), signal: Segmentation fault Using host libthread_db library "/lib/libthread_db.so.1".

Thanks for the bug report! @Hugo: reminds me a bit of bug 311092. The present report is for KDE 4.9.5, which includes your patch for that bug. This means that we can now be sure that the destructor of DolphinApplication, where the crash happens, is executed *before* the main() function is finished. Do you know anything that might have deleted a TileSet from the cache before that, leaving the pointer in the crash dangling? Thanks! BTW, you should be able to choose the default file manager in the System Settings.
Dear Frank! Thank You for the quick reply. Yes, I used System Settings to switch back to Dolphin. I'm not really sure *what* caused the crash, because all of above happened in rather quick succession: Plugged in Garmin 210; Opened file manager; closed Konqueror (because i wanted Dolphin); started Dolphin and opened "/mnt/media/Garmin/..."; started SportsTracker; read data from Garmin device; glanced at data; closed SportsTracker; crash! Best regards, Pär Johansson

I'm pretty sure there is no TileSet deletion in Oxygen itself (As a matter of fact, a grep -i delete throughout the oxygen codes shows that we don't delete much things ... ). We call, new TileSet, store them in caches, and let Qt cleanup the mess itself. Maybe its just a Qt bug ... (or me not knowing how to use the caches). > BTW, you should be able to choose the default file manager in the System > Settings.

Created attachment 81975 [details] New crash information added by DrKonqi dolphin (2.1) on KDE Platform 4.9.5 using Qt 4.8.3 - What I was doing when the application crashed: I had two external USB devices connected, a tablet and a USB HDD, I was copying several files from the HDD to the tablet. I noticed that on one of them I selected mov not copy so I paused it. Once the other transfers were complet I then kiled the transfer, thats when it crashed on me. hope this is of some use :) I'm using Mint 14 -- Backtrace (Reduced): #7 QVector<QPixmap>::free (x=0xa467be0, this=0xa5ee5cc) at /usr/include/qt4/QtCore/qvector.h:466 #8 0xb049f9ee in ~QVector (this=0xa5ee5cc, __in_chrg=<optimized out>) at /usr/include/qt4/QtCore/qvector.h:124 #9 ~TileSet (this=0xa5ee5c8, __in_chrg=<optimized out>) at ../../../libs/oxygen/oxygentileset.h:77 #10 Oxygen::TileSet::~TileSet (this=0xa5ee5c8, __in_chrg=<optimized out>) at ../../../libs/oxygen/oxygentileset.h:77 #11 0xb04dbb0f in clear (this=<optimized out>) at /usr/include/qt4/QtCore/qcache.h:139
Can anyone still reproduce this crash with more recent versions of Dolphin/KDE? I think I haven't seen a report for anything newer than KDE SC 4.9.5. Thanks for your help.

No response -> closing. Thanks for reporting this bug, please reopen the report if you can still reproduce this behavior with newer versions of Dolphin.
