Thanks for reporting this. On a production site you'll have to disable error reporting (just log them in the log file - I guess this is what you are already doing?) On the other hand I don't see any fatal error there - just notices and most of them come from the joomla framework and not from the plugin.
I'll try to reproduce that and fix it.
