[libvirt] segment fault from libvirtmod

Hi, The Makefile.am in python forget to add probes.o if WITH_DTRACE but after I added it and tried to connect, using libvirt.open("qemu:///system") in python , it reported: "segment fault" I tried to figure out, but failed. If anyone can help this, thanks. The following is the backtrace: #0 0x0000003c62a810a4 in free () from /lib64/libc.so.6 #1 0x00007ffff1836f29 in virFree (ptrptr=0x6a6a28) at util/memory.c:310 #2 0x00007ffff1849692 in virResetError (err=0x6a6a20) at util/virterror.c:387 #3 0x00007ffff13e2761 in do_open (name=0x7ffff7ed6444 "qemu:///system", auth=0x0, flags=0) at libvirt.c:1093 #4 0x00007ffff13e4d44 in virConnectOpen (name=0x7ffff7ed6444 "qemu:///system") at libvirt.c:1350 #5 0x00007ffff1824879 in libvirt_virConnectOpen (self=<optimized out>, args=<optimized out>) at libvirt.c:3637 #6 0x0000003c652dffbb in PyEval_EvalFrameEx () from /usr/lib64/libpython2.7.so.1.0 #7 0x0000003c652e0580 in PyEval_EvalFrameEx () from /usr/lib64/libpython2.7.so.1.0 #8 0x0000003c652e15a5 in PyEval_EvalCodeEx () from /usr/lib64/libpython2.7.so.1.0 #9 0x0000003c652e16d2 in PyEval_EvalCode () from /usr/lib64/libpython2.7.so.1.0 #10 0x0000003c652fb9ec in ??
