Model fails running after restoring from checkpoint

After creating a parameter file using:
LOAD_FROM_CHECKPOINT = True
CHECKPOINT_LOAD_FILENAME = '"param1_CP.sqlite"'

the generation seems to be ok. then running produces a bunch of errors of this type:

Hm. Looks like two things: (1) there's a crash; (2) the code I wrote to print out nice stacktraces telling you where the crash happened isn't working right on Linux. So I'll have to fix (2) first, which should then tell us more about (1).
