It doesn't die, but just hangs indefinitely.

What's funny is if I purge my entire ~/Documents/Energia/libraries/ folder, it's fine, but none of my libs are there.  Adding any one of the libs I had in there makes this error come back.

Nothing about those libraries has changed in the past 2 days... making this even more puzzling to me.  Energia had no problem with them before.  It worked earlier today, and just this evening I tried someone's sketch from IRC, which compiled but didn't seem to do much, however after disconnecting my F5529LP and trying to attach my Tiva (TM4C123), I noticed that error.

I tried purging ~/.energia including its preferences.txt file, all it does is ask me where to store the sketches, and when I select my old ~/Documents/Energia folder, it proceeds to bomb with that error again.

FWIW, energia 11 has no problem starting.
