Thanks for the bug report. Looks this actually only used to work by accident (oops!), in that @children was an empty array for files, and the change in 84fde64 "fixed" this by leaving @children for files as nil. The fix is just to add an if dir? to Dirent#each_child - will push that fix later.

Should be fixed now.
