Unhandled error in MediaScanner. System.ArgumentNullException: Value cannot be null (1 Viewer)

I am not sure if this is the correct location to post this but I have been having issues with movingpictures giving me
the following error. This is with MP 1.3.0 Alpha which I know is not probably supported yet, so hopefully it will help with the development.

When trying to retrieve matches for new movies it hangs and never receives any results, when I select to add as a blank editable movie, or rescan with custom string I get the error. Restarting the importer gets the same results.

I found a resolution to this issue has already been posted before, the movingpictures.db3 file had some corruption in it, and going to a previous backup resolved this issue.
