Fatal error: Uncaught TypeError: array_merge()

Suddenly got fatal error in both front-end and Manager when working on the site. Solved by manually emptying core/cache.

Step to reproduce

Occurred when editing a chunk or a Fred element

That looks like the lexicon cache file may have gotten corrupted. Unless that's a common/reproducible error, I don't think that's something in our control.

Should be fixed in #213
