Comment 5 Joris Guisson 2010-06-20 00:20:45 UTC 
Could you post the last 10 lines of your log file (~/.kde/share/apps/ktorrent/log) after a crash ?
Comment 6 Helmut Pozimski 2010-06-20 02:37:57 UTC

Comment 7 Joris Guisson 2010-06-21 20:11:51 UTC 
Fatal IO error: client killed

Means X closed the connection on ktorrent, that is not good.
Comment 8 Helmut Pozimski 2010-06-25 21:49:39 UTC 
If only the original bittorrent protocol is enabled, ktorrent runs as stable as alway so this bug seems to be connected to the implementation of the utorrent-protocol.
Comment 9 Joris Guisson 2010-07-09 19:44:35 UTC 
Upgrade to 4.0.2, it should be fixed in that release
Comment 10 Helmut Pozimski 2010-07-11 00:54:46 UTC 
Confirmed, after the update to 4.0.2 utorrent-protocol is working properly. No crashes so far.
Comment 11 Helmut Pozimski 2010-07-14 20:34:33 UTC 
Created attachment 49150 [details]
New crash information added by DrKonqi

Unfortunately it seems the bug was closed too early. The crash now happens less frequently but the bug seems to be still there. Another backtrace of 4.0.2 is attached, I don't see much of a difference but maybe it is helpful to you.
Comment 12 Joris Guisson 2010-07-15 10:57:07 UTC 
It's an XIOError

I haven't got a clue how to fix these

It also has nothing to do with the original problem here.
Comment 13 Nicolas L. 2010-07-19 20:24:56 UTC 
*** Bug 245158 has been marked as a duplicate of this bug. ***
Comment 14 Christoph Feck 2010-09-01 18:54:52 UTC 
Joris, the XIOError usually means the program was aborted in a different thread (in case of comment #11 it is a crash in thread 9).
Comment 15 Joris Guisson 2010-09-02 22:01:37 UTC 
If the program gets aborted in a thread due to a segmentation fault or an abort call, you can't have an XIOError, because the program will immediately be terminated by the kernel.
