[Bug 1221735] Re: upgrade from 0.25 to 0.27 failed
I had exactly the same problem and also found /etc/mythtv/config.xml was
zero length, but the error persisted after correcting the file.
Turned out that I didn't have xpath installed (libxml-xpath-perl) and
the mythtv-database package's postinit script suppresses errors from
xpath.
libxml-xpath-perl is a dependency of mythtv-common, but not mythtv-
database. I'm wondering now if it's simply because I tried using apt-get
upgrade initially instead of dist-upgrade.
