[virt-tools-list] bug or not

[Wen Congyang]

When I debug libvirtd, the virt-manager will Segmentation fault.

Steps to reproduce this bug:
1. debug libvirtd add a breakpoint in the function qemuMonitorOpen()
   # gdb /usr/sbin/libvirtd -p pid
   ....
   (gdb) b qemuMonitorOpen 
   Breakpoint 1 at 0x465150: file qemu/qemu_monitor.c, line 594.
   (gdb) c
   Continuing.

2. start guest OS
3. let libvirtd continue to run in gdb

This behavior is right or a bug?

Here is the log of virt-manager:
