[e2]

IO.popen("html2slim", 'r+') do |io|
  io.write ""
  io.close_write
  puts io.read
end

Crashes with:

System:

hpricot (0.8.6)
html2slim (0.1.1)
ruby 2.2.0p0 (2014-12-25 revision 49005) [x86_64-linux]

Probably a hpricot issue, but hpricot is no longer maintained AFAIK.

Could be easily fixed in a PR. Any chance you can try it out?
