Thanks all. 

Looking at the user's *original* data files, when I try to open them in Mesquite, not only is there a taxon label mismatch between matrix and trees, but Mesquite kicks out an error saying something about detecting a reticulation in the tree (???). At any rate, I cleaned up the original files so that Mesquite no longer has any issues.

After getting Rutger's feedback, I tried deleting all matrices and trees from the problem study (which should delete all associated taxon labels), and then completely re-uploading with fresh, and fixed, datasets. But the error persisted. So in the end I created a new submission, uploaded the files, and that works fine. 

> Indeed, the TaxonLabel.taxonLabel property property is nullable (why?), so this seems to be a legitimate situation and the fact that the code assumes that it can never be null is a bug. I fixed this and committed it to trunk. I haven't had a chance to rebuild, so I'm hoping it compiles.

Thanks for doing that -- unfortunately I went ahead with creating a new submission and deleting the old files before seeing that you made this fix.

Yeah, that has to do with me converting the submission back to "in progress" so that I can mess with it. 

But now it has been deleted, so you should get a "no results" return.
