Installer crash - cannot readglobal/config_exec_params

I've had a weird crash in the installer a few times now over the last
two or three weeks, though it seems to be somewhat unpredictable. I
can't quite figure it out, hence this post.

It occurs towards the end of the installation, I think when the PLs are
being installed (pretty sure it's not the contribs as I saw it once or
twice before they were added) which happens immediately after the
service has started. Basically a windows error pops up saying
postgres.exe closed unexpectedly because of an error. The installation
continues regardless, and leaves me with what appears to be a completed
installation and running server. All the PLs are there as appear to be
the contrib modules.

This time though, I noticed an odd error in the server log, right at the
beginning:
