Comment 7 for bug 416100

> Command 'mythtv' still crashes like reported in first post, maybe it is not intended to run directly?

That is correct. It is an unfortunately named test application. mythtv-test would be an infinitely better name.
Even still, upstream has corrected the crashes of this app in http://svn.mythtv.org/trac/changeset/21893, which will be included in the next sync upstream.
