From the line numbers above it looks like something in the calibre code that is failing since the last line in the plugin is to get metadata for all books in the database. That makes it hard to debug in the plugin. It could be a book with a bad path, or some connection issue with the device.
You could try running calibre in debug mode and see if it tells you anything more. Stop calibre, then on the command line change to a directory you have write permission in, then run "calibre-debug -g > out.txt". Look at the last few lines of the out.txt file to see if it gives any more information on the problem.
