           Summary: Lync calls crash Pidgin using SIPE plugin
    Classification: Platform
           Product: GStreamer
           Version: 1.4.1
        OS/Version: Linux
            Status: UNCONFIRMED
          Severity: normal
          Priority: Normal

Some details from previous bug 724244:
{
The Pidgin SIPE plugin to connect to Microsoft Lync servers will crash if a
phone call is attempted. The backtrace seems to indicate an issue in
gst-plugins-ugly. You may find backtraces in the fd.o or sf.net bugs.

See these bug reports for more information:
http://sourceforge.net/p/sipe/bugs/217/
https://bugs.freedesktop.org/show_bug.cgi?id=71253
https://bugzilla.redhat.com/show_bug.cgi?id=1028784
}

My personal observation is that pidgin will crash only if somebody tries to
call me directly (an incomming call). But once I call somebody, it doesn't
crash, works fine.
The problem is present still from older versions even up to the current stable
1.4.1 one.

As can be seen on one of the provided URL:
https://bugs.freedesktop.org/show_bug.cgi?id=71253 , the farstream developers
already pointed with finger to gstreamer to be the responsible for these
crashes.
But Michael Cronenworth in the previous bug 724244 said he made some own
tracing of the problem back to the farstream again, and he made some patch
"https://bugzilla.redhat.com/attachment.cgi?id=925254" for older version of
farstream 0.1.2.
Therefore it is still unclear which of those two - gstreamer or farstream - is
truly responsible for the crash.

Regarding providing you further debugging details (Full debugging symbols for
all involved libraries would be good. Perhaps also run pidgin in valgrind to
see if it picks up anything.), I'm affraid I can't as I'm not that skilled with
debugging, but I'll try ask that Michael, which looks like a skilled "probably"
developer.
