This is in my crontab file:

00 07   * * *     ~/bin/Hpodder.cron.sh

If I run that script (which calls hpodder & does a few other things
like renaming some long filenames & normalizing audio volume) from a
terminal (including screen), I do not get the error.  But the strange
thing is that I've only been getting this error since reinstalling the
OS (but keeping my home directory intact) after a hardware fault.

I can't remember what went wrong last time I tried it, but I'm trying
it again now.
