With svn revision 857856 ktorrent is crashing.

There are no steps to reproduce this, since crash seems to happen when I'm not touching it.

Crash report:
http://files.myopera.com/kriko/files/ktorrent.kcrash.gz

Try rev 858744, should be fixed in that version

Yesm it works. Thanks!

I just compiled and installed the latest svn revision 860288 and it is crashing for me. Could you please tell me how I can create such a crash report?

It should launch crash application automatically - there you have option to save crash report.

Well on my installation it does not start automatically. I think its not installed and now Im looking for the right package to install it.

Sure, you should install kdelibs-dbg and dbg, then a crach will popup a crachlog.

Those packages are installed but there is no such crash report dialog. I have also tried to run ktorrent via gdb with the nofork option but still no report.

Linkin: probably it is not crashing then, maybe it shuts down cleanly?
What are you doing exactly when this "crash" happens?

Which svn are you using? KDE4 or KDE3 version?

You are right kriko this might be the case. Im using 'ktorrent-svn 860288' and KDE 'Version 4.1.1 (KDE 4.1.1) (KDEmod)' on ArchLinux.

What I do is: I start ktorrent and have one paused torrent in it. Tracker is the piratebay. On the first attempt it fails to connect to the tracker and the new symbol is indicating the problem with the tracker. Then I manually refresh the tracker and it connects. It is always like that with the two attempts needed to connect to a tracker its also the same with the latest stable release. Then it starts downloading and uploading and so I send it to the systray. It stays there for about 2-3 minutes and then its gone. I always thought it was a silent crash but when I launch ktorrent from the console there is no message about any error.

Confirmed with r860834 (SIGSEGV). Backtrace below:
