SuSE Linux: Unable to add install source

[ATC]

When trying to add or replace an install source, yast fails with an error message about being unable to parse XML data.

[ATC]

1. Verify that the new install source actually still exists and contains a "repodata" subdirectory as needed by yast.

2. Clean the cache with the command 'rug cc'.

3. Restart the ZMD daemon with the command 'rug restart'.

4. Try adding the new source at the command line. Example:
'rug sa --type=zypp ftp://full.url.to/your/repo/' this-repo-name'

(replace 'this-repo-name' with something meaningful, like 'ftp-install' or 'mike-rpms' or whatever)
