Created attachment 68830 [details] New crash information added by DrKonqi plasma-desktop (0.4) on KDE Platform 4.8.00 (4.8.0 using Qt 4.8.0 - What I was doing when the application crashed: I can reproduce it also here on a x86 system. I had my external usb hard drive connected when logging in to kde when this crash appeared. It happens everytime. -- Backtrace (Reduced): #7 0xb6d340d8 in QObject::~QObject() () from /usr/lib/qt4/libQtCore.so.4 #8 0xb192531b in QDeclarativeBoundSignal::~QDeclarativeBoundSignal() () from /usr/lib/qt4/libQtDeclarative.so.4 #9 0xb1925372 in QDeclarativeBoundSignal::~QDeclarativeBoundSignal() () from /usr/lib/qt4/libQtDeclarative.so.4 #10 0xb6d2e931 in QObjectPrivate::deleteChildren() () from /usr/lib/qt4/libQtCore.so.4 #11 0xb6d340a1 in QObject::~QObject() () from /usr/lib/qt4/libQtCore.so.4
I also can reproduce this. Plasma crashes, if a usb-stick is inserted during login. Kde is 4.8, on sabayon. Here is a trace: http://pastebin.sabayon.org/pastie/8373 (tracebacks seem to vary on this one).
In my case, it crashes randomly when a mobile HDD on USB is also removed by ejecting it. But not always, just sometimes.
Apparently, there is a behavior specific to the file system: - when NTFS, it crashes after login when already attached, but doesn't crash when I attach the device after the login - when ext3/4, it crashes in all the cases
Thank you for this crash report and helping to improve our software. Unfortunately we were not able to work on this specific report yet. Nowadays the version this crash was reported against is no longer maintained and this makes it very difficult to work on this report as the source code might have changed and the information in the backtrace is no longer valid. Also it is quite likely that this problem got fixed in a later version. Crash reports are very often reported multiple times. If you are able to reproduce this crash with the latest version of KDE Plasma (4.10.3) please reopen this report and adjust the version information in the dropdown above and please also include a new backtrace as generated by the crash reporting tool. Please also make sure that the steps on how to reproduce the crash are precise and correct. Thank you!
