Missing validation on tag name (can be empty)
Some guy on the XBMC forum has managed to create an empty tag (see http://xbmclogs.com/show.php?id=182355). This should not be possible since a tag with no name makes no sense.
It could be ignored in the pvr.tvh addon but that seems like an unnecessary hack (XBMC ignores it anyway).

Most likely the user manually hacked the configuration files or possibly something went wrong during config migration?
But yeah a simple validation on load would probably not be a bad idea. The only thing I'd say is you start here and you'll end up with needing validation all over the shop! TVH generally takes a pretty light approach to configuration validation, there are various reasons for this (mainly because we're lazy), but also because its intended to be used by people that have a vague idea of what they're doing but checks usually exist at point of entry rather than when loading the config.
