A similar script to this was used in the mythtv deb package. It causes errors like: "errror creating /.qt" This error in itself seems benign. The cause of this error is the HOME environment setting not being set correctly. This caused more problems for tv listings updates that mythtv calls, or any other program that mythtv calls and assumes it can write files to the home directory.
A simple fix, put
HOME=/home/mythtv
after the USER=mythtv line.
