Some PVD threads seem to crash. Whatever, after looking through this bug report it doesn't really help me, either. It just shows your system environment, PVD threads, and other programs running on your computer while the program crashs occured. It might help nostra, of course, who is the author of PVD. But for the time being you might want to delete it from your post. It doesn't show passwords or something but gives away a lot of information about your computer.
I'm not really sure what happens and how to solve this.
I would download the portable version of PVD (just put it in some folder on your desktop for testing purposes) and try to add a movie to a fresh database (without the old plugins and scripts installed). At first, try to add a movie "by hand", not by importing anything. Then try to add one from file or internet. Then try it on an imported database of yours. Then try it with old plugins and scripts added to the scripts/plugins directories. And so on. Just to narrow down the cause of the problem.
Another idea would be to backup and then optimize your imported database. You will find these functions in the "Administraton" or "Tools" submenu (after clicking the "Personal Video Database" button). For optimizing the database I would at least choose to delete all invisible movie and person orphans and also choose the garbage collection (you can check these options in the "Optimize database..." menu). Doing that should have the database rebuild. That might give a cure if there was something strange hidden in your database structure.
