This bug will cause the dest get a unexpected value.
Example:
[root@yds-pc libvirt]# virsh
Welcome to virsh, the virtualization interactive terminal.
Type: 'help' for help with commands
'quit' to quit
virsh # connect
error: Failed to connect to the hypervisor
error: internal error Unable to parse URI �N�*C
Please someone give me a comment. Thanx~
