Cannot remove empty directory

[Michael Hipp]

I'm trying to delete an empty directory - normally not a particularly 
esoteric task :-)

   $ ls -lah
   drwx------   1 michael michael    6 2005-06-15 14:10 apps
   [snip]
   $ rmdir apps
   rmdir: `apps': Directory not empty
   $ ls -la apps
   total 4
   drwx------   1 michael michael    6 2005-06-15 14:10 .
   drwxr-xr-x  20 michael michael 4096 2005-06-15 14:10 ..
   $ rm -drf apps
   rm: cannot remove directory `apps': Directory not empty
   $ rmdir --ignore-fail-on-non-empty apps
   $ ls -lah
   drwx------   2 michael michael   17 2005-06-15 14:15 apps
   [snip]

Can't do it as root either. It's empty but it ain't ("total 4"). What gives?
