Pidgin backtrace log

Description of problem:
Pidgin crashes when you run it.

Version-Release number of selected component (if applicable):
2.10.7-2.fc18 (libpurple 2.10.7)

How reproducible:
Every time.

Steps to Reproduce:
1. Run pidgin with sipe-based default profile

Additional info:
A ticket has been opened in pidgin bug ticketing system, however they claim it is the issue in sipe plugin.


Comment 1 Stefan Becker 2013-03-27 12:32:32 UTC
The bug entry and backtrace doesn't contain enough information for me to work on this issue. I only see one function referenced from SIPE source code (sip-transport.c:1592) but without a version information I can't match it up the the source code visible to me.

- what is the version number of pidgin-sipe RPM installed on your machine?
- did you maybe compile pidgin-sipe yourself? If yes what release version or git commit?
- if you are not using latest 1.15.0 package from F18, can you reproduce the problem after upgrading?
- if you can still reproduce it with 1.15.0, can you provide a backtrace from a non-optimized version? E.g.

  $ tar xf pidgin-sipe-1.15.0.tar.bz2
  $ cd pidgin-sipe-1.15.0
  $ CFLAGS="-g -O0" ./configure
  $ make
  -> install the generated libsipe.so as root

- if you can still reproduce it in the previous step, can you try to reproduce it the latest git HEAD?

and PLEASE PLEASE PLEASE run "pidgin --debug" and attach the log output too, so that I have some context where the crash actually happens.

Name        : pidgin-sipe
Version     : 1.15.0
Release     : 1.fc18

Comment 3 Artur Cuvasov 2013-03-27 12:42:08 UTC
I forgot to mention it here... pidgin -d runs without any issues.

> I forgot to mention it here... pidgin -d runs without any issues.

This will make this difficult to debug. What is the log output without -d? And please try to reproduce with the non-optimized version.

Comment 5 Artur Cuvasov 2013-03-27 12:57:15 UTC
I have sent you "with -d" by mail . Without it's just:

Pidgin 2.10.7-2.fc18 has segfaulted and attempted to dump a core file.
This is a bug in the software and has happened through
no fault of your own.

Comment 6 Artur Cuvasov 2013-03-27 13:46:31 UTC
A short summary of what we have discussed by mail:

Recompilation did not show any problematic areas. I am able to run "pidgin -n", and then log in manually. Pidgin does not crash. It only crashes when pidgin is trying to connect automatically after I run it.

At the moment I downgraded to purple-sipe and pidgin-sipe 1.13.3, as the problem appeared after upgrading to 1.15.0

Comment 7 Stefan Becker 2013-03-27 15:59:02 UTC
Pushed proposed fix for inclusion in 1.15.1 release. Please verify.

    transport: fix use-after-free accesses
    This is a proposed fix for the Heisenbug crash reported here:
    Valgrind log showed invalid read/write accesses to the already freed
    transport data structures in the following cases:
    - sip: during redirect
    - http: potentially on server initiated close
    - http: on user initiated close
    With this patch my valgrind log no longer shows any invalid accesses
    from the SIP/HTTP input routines.

Comment 8 Artur Cuvasov 2013-03-29 08:55:52 UTC
The patch has solved the issue, pidgin does not crash anymore.
