what is a "special machine" ?

also, generally there's no need to say "The patch fixed it".  the fact that 
you've described a bug and have a patch implies that this fixes things.

i think you mean "no" instead of "None"

"Not any" -> "No"

"using" -> "use"

change the ", the" to ". This".

looks like you mixed spaces & tabs.  only use tabs.
