This happens at least 50% of the time on me, since about a month ago. Whether I use a right-click or the red X to stop seeding a downloaded file, KTorrent crashes out, with no useful error. I upgraded to 2.2.4 today, but KTorrent crashed the first time I cancelled a torrent.

Any ideas where to look for the source of the problem?

Do you have ZeroConf peer finder enabled? I've got a similar report in Ubuntu (with no traceback) that ZeroConf on results in crashes when starting/stopping torrents.

Thanks! I had that problem also.

If I started multiple torrents (even individually) ktorrent would just crash, with no error

disabling zeroconfig fixed it

How can i disable Zeroconf peer finder?

Thx i found it. Admins you need to do something. Zeroconf peer finder is the reason of ktorrent crash.

Hmm this doesn't seem to be a coincidence anymore. There's probably another crasher bug in ZeroConf again. George, any ideas?

Has anyone who has this issue tried running ktorrent in gdb, so when it crashes you can get a backtrace?

Because I have the zeroconf plugin enabled since 2.2 and have never had any problem canceling torrents.

Seems to work better now alright. Thanks for the tip

User gave me a GDB log

Damn, I thought I fixed all the zeroconf bugs.

I will see if I can reproduce it.

Hmmm....

I have been suffering the same problem, plus I have noticed that minimizing the window seems to cause Ktorrent to crash.

My temp solution has been to never minimize the Ktorrent window or send to run in the task bar... not really a fix, but it has been my work around. I am constantly grabbing Twit netcasts, Revision3 tv, hak5 tv, Geekbrief tv, and many other audio/video netcasts so the client pretty much runs fulltime.

This torrent box if you will, is a dedicated box that saves to my NAS server and does not do anything but torrents, so not a big deal on my part to leave the window open all the time, but I do concur that there does seem to be a bug that appears when zeroconf is enabled.

Figured I would share my two-cents regarding the report of this bug. Otherwise excellent and reliable torrent client!

Minimizing seems fine, but I've gotten 2 more ZeroConf crash reports in Ubuntu land -- I strongly suspect there is indeed a problem in the ZeroConf plugin.

Ubuntu here also... could it be an Ubuntu issue or are other distro's encountering the same problem? If it is only Ubuntu the problem may be an Ubuntu handling issue and not Ktorrent... or at least not directly Ktorrent.

I bring up the Ubuntu only idea as bassmadrigal mentioned no problems running Slackware

I did have it crash a while ago, but I just hadn't killed ktorrent to install the 2.2.4 version, and I didn't notice anything in the backtrace about zeroconf.

Just an FYI, I remember when I was building this that I had a really hard time building zeroconf. I ended up having to do a lot of things so I could get it to compile and have ktorrent recognize it. Unfortunately it was long enough that I don't remember what I did.

I am almost wondering if this has to do with the zeroconf package that ubuntu has put out. Maybe if you recompiled zeroconf then that might fix your issues. I am running the latest stable 0.6.21.

I have been running 2.2.4 since it came out without any crashes, and I pretty much run it 24/7.
