Comment 1 Joris Guisson 2005-09-17 13:58:05 UTC
Run ktorrent from the commandline in debug mode : 
 
ktorrent --debug 
 
When it crashes, send me the log file (should be in ~/.kde/share/apps/ktorrent)

Logfile from a crash without message
Comment 3 Joris Guisson 2005-09-19 20:32:47 UTC
The log file ends in the middle of a line, which is not good.

Was there any message on the commandline, apart from the debug output ? 

The crash with backtrace, seems to be in Qt.

Comment 6 szczur470 2006-03-26 14:25:14 UTC
Hi, I've got the same problem, but on SuSE 10 (or I think it's the same). But what I/we can do to avoid crashes?
Sorry if I shouldn,t write here.
Comment 7 Joris Guisson 2006-03-27 18:27:06 UTC
What version are you running ? This is an old bug and fixed a long time ago, it probably is not the same as the bug you are experiencing.
Comment 8 Helder Ribeiro 2007-05-19 13:23:02 UTC
I have the same problem using ktorrent 2.1 on kde 3.5.6 and Kubuntu 7.04 (Feisty). I'm running it with --debug now as you suggested then I'll post it here.
Comment 9 Joris Guisson 2007-05-19 13:41:17 UTC
Backtrace ? 
Comment 10 Helder Ribeiro 2007-05-20 19:10:25 UTC
Created attachment 20641 [details]
output of ktorrent --debug that resulted in the crash

I get this error frequently and it's always when I'm not paying attention to
ktorrent so I don't know how to reproduce it. But it is consistent.
Comment 11 Joris Guisson 2007-05-20 21:35:10 UTC
It's probably 144416, and this is also fixed, upgrade to 2.1.4

Comment 13 Adrian Christofferson 2008-04-30 23:11:18 UTC
Hi Guys, i get the same error message KTorrent causes signal 11 
there appear to be links to other similar issue throughout this forum but i cant seem to find where the resolution has been posted, anyway i have included the backtrace just in case it is something different BTW i am running Kubuntu Gutsy Gibbon and KTorrent version 3.5.8.
