UPDATE: I dug around inside the troublesome files and saw that a couple of them were applying metadata with defunct file paths so I looked inside the hierarchy and found some file nodes swimming around in there. I deleted the nodes and hey presto. The process goes off without a hitch.
Some of the file nodes were pointing to PSDs that do not exist, jpegs or TGAs. Why would this cause Maya to crash though? Can file nodes become corrupt or would Maya choke on defunct pathing under heavy iteration? Some of the nodes were perhaps under File and were referencing PSDs which could be an issue or vice versa.
