Anton added a bit of clarification -- he posted to bup-list that in his
case pylibacl reports the IOError with errno == 0 when "x" above refers
to a group that doesn't exist on the current system.

i.e. if you use x = y.to_any_text() on a machine, and then take x to
another machine[1] that doesn't have some group that's referred to by x,
and then call ACL(text=x), you'll see the exception with errno == 0.

[1] ...or presumably the same machine, if the group has been deleted.

Thanks again
