Fails with attached file

Apologies for not being able to narrow this bug down farther, but
here's what I have. When I try to minify the attached file, I get the
following output:

test2.hs: Prelude.head: empty list

The files are in the repo as test/unminified/issue7.js and test/unminified/issue7.hs

Narrowed it down to

var hljs=new function(){function k(){if(k.called){return}k.called=true;var r=document.getElementsByTagName("pre");for(var p=0;p<r.length;p++){}}}();

Updated on hackage as version 0.0.16

Verified as fixed, thank you!
