TypeError: list indices must be integers, not str

Sometimes I get this error while compiling a template, but not always. I wonder if this library is not thread-safe?

Traceback (most recent call last):

@dobesv do you have an example template where this happens sometimes?

[pg1671]

I get the same error occasionally. Have not had time to look into it further as it is not that often.
