We encountered the issue gohugoio/hugo#8627 seemingly random, until we realized that the environment variable
GIT_TRACE
was enabled for debugging.The parsing logic does not handle the additional output very well and therefore panics with the "index out of range" error.
The simplest solution would be to ignore all environment variables.
However, I'm not absolutely sure that this has no unintended side-effects.
