Yeah, I noticed that 'bug' and tried to figure out what's wrong with it.
I couldn't find out! The problem part is something liske this:

stat ($existsn_dir)

if (-d _) {
  delete_dir;
}

else {
  delete_file;
}

What's the oddest part, it works PERFECTLY in every other situation. Try
to make a clean file and call that same function on that same file, it
works! '_' (underscore) symbol in perl means cached value of previous
stat call but we have somehow turned off that caching. I wouldn't call
it a bug though, I think it's more like 'gotcha' :)
