 ..Crud

 Yes, Attempting to delete null causes problems like that.. It gets
 interprated as its asking you to delete CWD or / by the underlying
 filesystem functions.

 and an undefined variable(ie. $null) does that.

 ...2.8's filesystem abstraction files includes a patch already to prevent
 deletions of null.. But obviously, 2.7's doesnt, During an upgrade from
 2.7 to 2.8, The 2.7's filesystem files are used (instead of new ones from
 2.8), The end result, is.. this..
