Thanks for taking the time to report this bug. Without a stack trace from the crash it's very hard to determine what caused it. Can you get us a stack trace? Please see http://live.gnome.org/GettingTraces for more information on how to do so. Thanks in advance!
In response to email from user: can you get us a stacktrace? They look like the examples at http://live.gnome.org/GettingTraces/Details#learn-about-stacktraces and strace output isn't the same thing unfortunately. http://live.gnome.org/GettingTraces/Details#obtain-a-stacktrace has more details on obtaining one. We don't in general respond to direct emails, preferring to keep all communication regarding bugs on the Bugzilla as much as possible.

Um, that's the *strace* output again, which is the *wrong* thing. We need the output from gdb or bug-buddy, which can be retrieved as detailed at http://live.gnome.org/GettingTraces/Details#obtain-a-stacktrace. The strace output is for the most part effectively worthless from the point of view of actually figuring out what the heck causes your crash.
Hi, sorry for wasting you time - I had the wrong soundconfiguration that was the whole problem.
(In reply to comment #5) > sorry for wasting you time - I had the wrong soundconfiguration that was the > whole problem. Still shouldn't cause a gstreamer crash. We'd quite like to get a stacktrace for this so we can catch this (possibly alerting the user that's something is wrong, but without crashing the whole program).
The errors are the result of configuring a non-working sound output (you should get better error messages, but that's another long-fixed bug (bug #471364). The criticals/warnings indicate a refcount bug. It is likely that this is a bug in pidgin's error handling (I've seen this pattern before). It looks like pidgin just unrefs an element/pipeline without first doing gst_element_set_state (element, GST_STATE_NULL);
hi, now I hope I get a stracktace. I have useing bugbuddy I hope that is okay: Starting program: /usr/bin/pidgin [Thread debugging using libthread_db enabled] [New Thread 0xb7230b50 (LWP 5833)] [New Thread 0xb51aeb90 (LWP 5866)] [New Thread 0xb489bb90 (LWP 5867)] [New Thread 0xb3e99b90 (LWP 5868)] [New Thread 0xb3698b90 (LWP 5869)] [Thread 0xb3e99b90 (LWP 5868) exited] [Thread 0xb3698b90 (LWP 5869) exited] [New Thread 0xb3698b90 (LWP 5870)] [New Thread 0xb3e99b90 (LWP 5871)] [New Thread 0xb2c96b90 (LWP 5872)] [Thread 0xb3e99b90 (LWP 5871) exited] [Thread 0xb2c96b90 (LWP 5872) exited] [New Thread 0xb2c96b90 (LWP 5873)] [New Thread 0xb3e99b90 (LWP 5874)] [New Thread 0xb2294b90 (LWP 5875)] [Thread 0xb3e99b90 (LWP 5874) exited] [Thread 0xb2294b90 (LWP 5875) exited] (pidgin:5833): GStreamer-CRITICAL **: Trying to dispose element play, but it is not in the NULL state.

First off: what pidgin version are you using, and what distro? Maybe you could run this from a command line / shell (gnome-terminal/xterm/konsole or the like): $ export G_DEBUG=fatal_warnings $ gdb /usr/bin/pidgin Welcome to gdb ... (bla bla) (gdb) run ... reproduce crash ... ... it should stop by itself ... (gdb) bt ... the output here is what we're after. All of it, not just the first line. (gdb) kill (gdb) quit If you're running debian/ubuntu (or a debian-based distro), please install the following packages first, if available: $ sudo apt-get install libgstreamer0.10-0-dbg gstreamer0.10-plugins-base-dbg gstreamer0.10-plugins-good-dbg pidgin-dbg If you're running a different distro, please try to install the equivalent packages (not sure what they're named, but probably similar and with a -debug suffix). This will make sure the stack trace contains debugging symbols. Without debugging symbols the trace is unlikely to be very useful.
okay is it debian and pidgin is 2.4.3#0 0xb7ffc424 in __kernel_vsyscall ()
+ Trace 212711
Ok, thanks for the stack trace. So here GObject complains about pidgin calling g_signal_emit() on a NULL pointer instead of an object, which is definitly a pidgin bug and needs to be fixed there. The other errors are most likely also pidgin refcounting bugs (or a missing set_state(NULL) on the pipeline), most likely in pidgin's error handling code (the code where it handles GStreamer errors). Please file bugs in pidgin's bug tracker (or against debian if you are using debian's pidgin packages). It would be good if you also installed full debugging symbols for pidgin if you do that, and there are packages for that available.
