Thanks for the report. Can you tell me what sort of file this was? It looks like this was an “injection” scenario — one language embedded in another — so I'm curious to know which language might have the bug here.

[jboilesen]

It happened in a pure .php file with only PHP code (but the project also has HTML, CSS and JS files).

[savetheclocktower]

Strangely, that counts because of the way that the PHP grammar is architected.

I see the bug here (assuming something that may return null is an array without checking it), but I don't yet understand why it happens. Still, I should at least make it so that it doesn't throw an exception.

I'm glad that it's sporadic instead of something that happens all the time. Still, if you figure out reliable reproduction steps, please let me know. Thanks!
