SIGSEGV in call_in_idle_cb (gdbusconnection.c)

Sun Oct 28 23:06:36 PDT 2012

Hi all,

I am trying to establish communication between two processes. Processes are
stable until the Dbus call is made.

When a dbus communication gets established, i am get a sigsegv signal
(segmentation fault ) my system starts rebooting. :(... which not
desirable.

i used a tool to find the trace and following is the trace.

Stack calltrace#FunctionArgs
