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 I forgot to mention it here... pidgin -d runs without any issues. (In reply to comment #3) > 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. 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. 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 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:
https://bugzilla.redhat.com/show_bug.cgi?id=928323
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.
The patch has solved the issue, pidgin does not crash anymore. pidgin-sipe-1.15.1-1.fc19 has been submitted as an update for Fedora 19. https://admin.fedoraproject.org/updates/pidgin-sipe-1.15.1-1.fc19 pidgin-sipe-1.15.1-1.fc18 has been submitted as an update for Fedora 18. https://admin.fedoraproject.org/updates/pidgin-sipe-1.15.1-1.fc18 pidgin-sipe-1.15.1-1.fc17 has been submitted as an update for Fedora 17. https://admin.fedoraproject.org/updates/pidgin-sipe-1.15.1-1.fc17 Package pidgin-sipe-1.15.1-1.fc19: * should fix your issue, * was pushed to the Fedora 19 testing repository, * should be available at your local mirror within two days.
