Description Robert Simmons 2011-04-13 17:34:38 UTC

Application: ktorrent (4.1.0)
KDE Platform Version: 4.6.2 (4.6.2)
Qt Version: 4.7.0
Operating System: Linux 2.6.35-28-generic i686
Distribution: Ubuntu 10.10

-- Information about the crash:
- What I was doing when the application crashed:

I had just finished downloading FreeBSD 8.2 iso images which downloaded flawlessly BTW (sha256 checksums fine).  And I clicked quit under the File menu and it crashes with a seg fault.

I did not get this version as an Ubuntu package, I compiled it from source, but there were no problems with the compile/install.

The crash can be reproduced every time.

-- Backtrace:
Application: KTorrent (ktorrent), signal: Segmentation fault

Comment 1 Robert Simmons 2011-04-13 17:40:32 UTC

I also started a thread on ktorrent.org's developer forum about this bug here:
http://ktorrent.org/forum/viewtopic.php?f=1&t=4044&p=20275#p20275

Comment 2 Joris Guisson 2011-04-13 18:27:22 UTC

Cannot seem to reproduce. Could you run it under valgrind ?

valgrind --log-file=vg.log --num-callers=50 /usr/bin/ktorrent --nofork

When it crashes, post the vg.log file here.

Comment 3 Joris Guisson 2011-04-13 18:28:39 UTC

Note that running under valgrind is slow.

Was this with a crash ?

Comment 6 Robert Simmons 2011-04-13 19:16:08 UTC

Yes.  It crashed and called DrKonqi to submit the crash report.  That's where the backtrace above came from.

Did you also compile and install libktorrent 1.1 ?

Comment 8 Robert Simmons 2011-04-16 17:26:10 UTC

Yes, I compiled and installed libktorrent 1.1 first.

Comment 9 Joris Guisson 2011-04-16 20:09:22 UTC

Is an older version of libktorrent still installed ?

Comment 10 Robert Simmons 2011-04-16 20:13:26 UTC

Yes. I have the 1.0.5 libktorrent installed.  It is the official ubuntu package, so it is not in /usr/local.  When I compiled the new version of libktorrent and ktorrent itself I made sure the path setting was /usr/local when I ran cmake for both of them.  That should prevent any confusion, correct?

Comment 11 Joris Guisson 2011-04-19 22:05:56 UTC

Things could get hairy with the plugins.

Try uninstalling libktorrent 1.0.5, and see what happens.

Comment 12 Robert Simmons 2011-05-14 20:32:37 UTC

Looks like that fixes the problem.
