That does seem buggy but I don't know enough to say for certain. 
I'd suggest filing a bug report anyway; the worst thing that can 
happen is that it gets closed. Unreported bugs can only be fixed 
by accident.

Tacking an .idup after .toLower seems to make it work, at least 
on dpaste (http://dpaste.dzfl.pl/8abed3d3ec6c). I would have 
thought both toLower and idup returned a normal string, but 
unsure.
