Description Jake 2007-12-02 05:48:08 UTC

Version:            (using KDE KDE 3.5.8)
Installed from:    Ubuntu Packages
OS:                Linux

After opening a webcam session over MSN, so that I am both sending from my webcam and receiving video from the person I am chatting with, Kopete will freeze after about two minutes of videochatting. Before that, the video which I receive will often be delayed. After two minutes, the entire application freezes so that I am not able to get a response from the chat window or the main window where you select people to chat with. I have to pkill it and restart it manually.
I am using a Creative Notebook webcam, spca5xx driver on Kubuntu 7.10. Kopete 0.12.7 on KDE 3.5.8. 2.6.22-14-generic kernel.
Webcam works fine in amsn.

Comment 1 Will Stephenson 2007-12-02 20:42:24 UTC

Please install debuginfo packages, strace kopete and attach the point where it freezes, and run kopete in gdb and obtain a backtrace when it has hung, if possible.

Comment 2 Jake 2007-12-02 21:34:08 UTC

I'm not really sure how to debug an application in this way, which is to say, I've only debugged my own code, and never needed to debug anyone else's compiled applications. I've never done any C/C++ development, so this is all new to me. Could you point me to a resource that would show me how to use strace and gdb to do this? Can I hook it up to a graphical debugger? What is the best IDE to use for this?

Also, it doesn't look like there is a debug info package for kopete in apt (though there is one for pidgin). If not from apt, then where and how can I obtain the debug info package?

Please let me know. Thanks.

Comment 3 Will Stephenson 2007-12-03 08:03:41 UTC

About debuginfo: I don't exactly where Ubuntu put it, but they do generate it.  Look for a -dbg package or -debuginfo with the same name as the package Kopete came in.  Perhaps you have to enable a specific repository.  Ask in Ubuntu specific support channels.

strace:
strace kopete --nofork &> kopete.strace

gdb:
gdb --args kopete --nofork
....
gdb> run
....
(when it is good and frozen)
CTRL-C
gdb> backtrace
....
(this is the bit I want you to paste here)
....
gdb> kill 
(kills the process being debugged)
gdb> quit

If gdb doesn't respond to ctrl-c at that point you may have to pkill it, in which case the strace output is useful.

Re graphical debuggers: KDevelop has one but I don't have any experience using it.  It is a wrapper around gdb so the principles should be the same.

Comment 4 Jake 2007-12-04 04:11:44 UTC

I asked on kubuntu forums:
http://kubuntuforums.net/forums/index.php?topic=3089308.0
"
you are right, there is not a dbg package for kopete in k/ubuntu.  not all packages have dbg packages along side them.  i suppose it'd be possible to file a bug on launchpad requesting the package be made available to k/ubuntu.  (mark it as wishlist).

or, if the package is in debian, you could file a bug and mark it "sync with debian".
"

Also checked apt-get.org:
http://www1.apt-get.org/search.php?query=kopete-dbg&submit=Submit+Query&arch%5B%5D=i386&arch%5B%5D=all
Turned up nothing, so package is not in debian.

What would you recommend I do now? Do I need to check the source out of svn compile it with debug enabled, then run gdb on that? Or can you think of any other way I can get the kopete debug package?

Comment 5 Jake 2007-12-08 03:17:25 UTC

Checked latest kopete out of svn last night. Compiled it with debug enabled. Here's the last output before it freezes and I have to Ctrl+C to kill it.

Comment 8 Cláudio da Silveira Pinheiro 2008-01-22 04:37:14 UTC

I'd like if you could do another little test, even a simpler one:

Add a Testbed account in your list;
Get online with the testbed protocol;
Open Kopete's configuration window, go to the video panel;
While the video panel is open, right-click on the Kopete icon in the system tray and go to Testbed account/Show my own video;
Let the thing running for 15 minutes;
Close the Testbed video window;
Close the video configuration window;
Quit Kopete.

The image from webcam must be updated while there's an open window showing it. Tested here with 3.5.x, 4.0.x and trunk, and everything went right.
I'm asking it because I suspect the bug resides in MSN protocol, not in protocol-agnostic video handler. I saw some weirdness with Kopete's MSN implementation of the video protocol, as video getting too out-of-sync with reality (by more than 2 minutes of difference). My bet is MSN queues frames to send (it sends video in a timeslice-based, hard-coded time fashion, independent of the available bandwidth) and those frames start to accumulate in the queue, eating more and more memory and after some given amount of time/RAM it simply freezes. I have no deep experience with the MSN protocol, but my wild guess is that it is the culprit. ;D

Please do the test and report back, so we can put the bug where it belongs.

Comment 9 Cláudio da Silveira Pinheiro 2008-02-05 15:44:48 UTC

Jake, I'm waiting for more info about this bug. I asked you in January 22nd to do a test, and I didn't get an answer back from you since then. This info is neccessary to fix the bug you opened in bugs.kde.org. Please do te test and report back so we can act upon.

Thanks in advance.
