astropy coordinates issue with session from December & double title

[aagoodman]

As the image below shows, there is a problem loading the glue session at https://drive.google.com/open?id=17NRK3B4L1FvMUT0PiS3kiPuOlFM3JANZ (@astrofrog should have access) now, which has something to do with astropy units issue, I think. Also (see screen shot) the "double title" issue we saw in our glue meeting yesterday seems to be present at the top of the error log screen too.

Actually, this is pretty urgent now--most (all?) of the older RadWave files won't open in my version of glue.
