FC6: yum problem: unknown url type: media

[Kevin Layer]

Some details.  If I add the `print' below to
/usr/lib/python2.4/site-packages/yum/sqlitesack.py:

class YumAvailablePackageSqlite(YumAvailablePackage):
...        
    def returnSimple(self, varname):
...
            c.execute(query)
            r = c.fetchone()
            self.simple[varname] = r[0]
            if varname == 'basepath':
                print "db query for %s returned %s\n" % (varname, r[0])

it prints this:

So, in the bad case, it's getting the media://... out of the database.

How do I verify that the sqlite database is OK?  Can it be rebuilt?

I've done "yum clean all" and uninstalled yum (actually, anything with
yum in the name) and reinstalled (with rpm).  Same deal.

The thought of going back to just rpm is a deal killer for me.
