[virt-tools-list] [virt-manager PATCH] Support incomplete .treeinfo files

[Martin Kletzander]

In case there was '.treeinfo' file available, virt-install was
forcibly getting image information out of the file.  For some
distributions (especially older releases, e.g. RHEL 4), there might be
'.treeinfo' file available, but with incomplete information.  Allow
fallback to default values even when '.treeinfo' file is found.
