Did a few more tests with different length recordings. 3 hours works, needs Timeout 1800 or rdimport exits with error. 3 hrs. 20 min. doesn't work, rdimport exits without error, cart is created and shows the full time in library, but only contains truncated audio (12 minutes, in this case. 150MB from a 2GB wav)
