Just upgraded to Omeka 1.4.2 and Csvimport 1.3.3 was installed. (I've successfully used Csvimport before the upgrade - we were at Omeka 1.2.x).
I upload the file, select the mapping columns and boom... I enabled error logging as requested and the result stack trace is below. I ran the test twice - same error.
