Vandelay stalls and gives Type error

[Tiffany Little]

Tested on 3.6.2 community demo server and a server running current master.

Attempted to load a file of MARC records in MARC Batch Import/Export. I set up a matchset, and set up the upload the same on both servers. I set it as:

Bibliographic Records
Test matchset
Match-Only Merge profile
Import Non-Matching Records-checked
Merge on Best Match-checked

On current master--but not the 3.6.2 demo server--I get this error in the console, and my upload doesn't progress beyond creating the queue.

I think this was something on my server. Marking as Invalid, and apologies for the noise.
