I guess you had a torrent transfer running? Also, do you have debug symbols installed? Lukas
Created attachment 70263 [details] New crash information added by DrKonqi kget (2.7.4) on KDE Platform 4.7.4 (4.7.4) using Qt 4.7.4 - What I was doing when the application crashed: Crash KGet when disconnect external USB disk with torrent files -- Backtrace (Reduced): #6 0x00007fb450fca3a5 in __GI_raise (sig=6) at ../nptl/sysdeps/unix/sysv/linux/raise.c:64 #7 0x00007fb450fcdb0b in __GI_abort () at abort.c:92 [...] #12 0x00007fb45292202e in QEventLoop::exec (this=<optimized out>, flags=<optimized out>) at kernel/qeventloop.cpp:214 #13 0x00007fb452926789 in QCoreApplication::exec () at kernel/qcoreapplication.cpp:1064 #14 0x0000000000429601 in main (argc=1, argv=0x7fff0f70d768) at ../../kget/main.cpp:168
Yes, torrent transfer is running. And Yes, DrKonqi install kdenetwork-dbg package.
An exception was thrown and not caught, resulting in an abort. We need to know where the exception is thrown. Given the fact that an external disk has been disconnected, I would put my money on a SIGBUS being caught by ktorrent and it then subsequently throws a bt::Error which doesn't get caught. Does KGet store the logging of libktorrent somewhere ?
Sure, KDEDIR/share/apps/kget/torrentlog.log Lukas PS: Thanks for the information, that's a place to start :)
I use Kubuntu 11.10 Where can I find this file?
~/.kde/share/apps/kget/torrentlog.log
Unfortunately, the backtrace doesn't contain much helpful information due to uncaught exception (not your fault). If you can reproduce the crash every time, please follow the guide[1] and try to run it under gdb to get a better backtrace.
