Description of problem:
1. Hitting "Next" after picking "Source/Binary RPM" in the File->Export dialog
doesn't register the first time (but does on subsequent clicks).
2. This evidently throws an NPE (causing an "Unhandled event loop exception" to
be echoed to the terminal).
Version-Release number of selected component (if applicable):
Steps to Reproduce:
1. See above
1. First click doesn't register
2. "Unhandled event loop exception" echoed to the terminal
First click registers; nothing echoed to terminal.
Closing this bug out due to its age and the assigned product.
