NullPointerException when using the TDMS exporter

Running base v3.1.1 with mev-launcher-1.9 binary (current base version and MeV version 4.7.3) on Centos6. Tried to export a bioassay set of two bioassays to a TDMS file for analysis in MeV and got a unnamed error with the following stack trace:

java.lang.NullPointerException

The workaround is to use the 'clone reporters' function for the experiment to create a cloned set of reporter annotations.
