Description Alexander Terekhov 2005-05-30 13:27:14 UTC 
Version:           0.10.1 (using KDE KDE 3.4.1)
Installed from:    SuSE RPMs
Compiler:           SuSE 9.3 installation compiler
OS:                Linux

After installing 0.10.1 (both source and pre-compiled) I get the SIGSEGV 11 when MSN goes online.
SuSE 9.3 / KDE 3.4. Before server software update MSN (in KOpete 0.10) worked fine.

Log is:

How can this be resolved?

Comment 1 Alexander Terekhov 2005-06-01 14:17:41 UTC 
Hi again.
The same issue I have after installing KDE 3.4.1 from SuSE updates (KOpete 0.10.2 respectively)
Comment 2 Thiago Macieira 2005-06-01 15:56:05 UTC 
Is this reproducible? Does it happen all the time?
Comment 3 Alexander Terekhov 2005-06-01 20:58:46 UTC 
Yes, it is - constantly (about 20 times I tried). I don't know whether it is reproducible on other workstations ;) At least I never seen MSN working in KOpete, starting with 0.10.1.
Configuration is SuSE 9.3 / KDE 3.4 (and now KDE 3.4.1)
Hardware is Asus L3C-S (I don't know whether this matter, but...)

I'm going to setup another workstation with SuSE 9.3 next days, so I'll let you know the results.  (This can of course be caused by distribution package set... on the other hand I have all online updates installed...)

For now, neither 0.10.1 nor 0.10.2 (with KDE both 3.4 and 3.4.1) work.
Comment 4 Laurent Dubuisson 2005-06-02 12:41:19 UTC 
Same problem on kubuntu on the KDE 3.4.1 with 0.10.2

Comment 5 Thiago Macieira 2005-06-02 13:53:29 UTC 
If anyone can get a backtrace with debugging symbols, it would certainly help. The topmost functions are shown as ?? in both backtraces, which doesn't really help us.

*** Bug 107833 has been marked as a duplicate of this bug. ***
Comment 7 George Staikos 2005-06-26 18:41:26 UTC 
I've seen it too, but I can't trace down where it's from and I cannot reproduce it.  I need a valgrind trace, but I suspect the crash is inside OpenSSL (which is very bad).
Comment 8 Graham Borland 2005-06-27 11:41:57 UTC 
Here's some valgrind output:

  That looks like an openssl bug still.  Can you build openssl with debug 
symbols and rerun?

Thanks
Comment 10 Thiago Macieira 2005-06-28 02:47:38 UTC 
Or SslLoginHandler::readSslData gave KSSL::read an invalid pointer.

  Right.. but no way to know until we see a debugging version of openssl run 
through valgrind I guess.  Or the old-fashioned debugging way. :-)
Comment 12 Olivier Goffart 2005-07-16 23:45:03 UTC 
We now use a new login handler which doesn't use KSSL directly anymore.
