A call to Finsert is not a system call.  And there's nothing
system-call'ish in the fact that a value that was supposed to be a
Lisp string is instead a list of strings.  I would rather suspect some
rare condition in the code that doesn't get handled correctly.

Well, then how about running Emacs under a debugger, and when that
happens again, looking around for the information I requested?
