Description Mark McLoughlin 2006-07-04 07:10:26 EDT
In virDomainParseXMLOSDesc(), cur->children can be NULL if the txt node is empty

[root@lak test3]# grep cmdline test3.xml

[root@lak test3]# gdb virsh
(gdb) run create test3.xml
Starting program: /usr/bin/virsh create test3.xml

Program received signal SIGSEGV, Segmentation fault.

614                     if ((txt->type == XML_TEXT_NODE) && (txt->next == NULL))
