Error: Skeleton.lua 445 related to local 'slotName'

kilopop

Using Corona simulator running the latest spine-corona example.
After 27 minutes the simulator crashes with the following output notice:

The Corona sample displays different skeletons. On which skeleton does it crash?

kilopop

The first one. That is, main.lua runs as provided in the new runtimes and is left alone. Eventually it crashes with this slot name error.

I've created an issue and noted a likely cause:
