Description

System Information
Windows 7 x64
Two GTX 580

Blender Version
blender-2.70a win64 hash f93bc76 same result
blender-2.72 rc1 win64 hash eb464ee same result

Short description of error
All other LoopTools operate (as expected) on selected vertices, Curve (unexpectedly, from an artists perspective) works on unselected vertices.

Before Curve tool

After Curve tool

Also, couple of times with 2.72 rc1 had “Python: VIEW3D_MT_edit_mesh_looptools” appear where LoopTools selection should appear

Exact steps for others to reproduce the error
With LoopTools Addon enabled
Open below .blend file
Press W
Systematically try each of the LoopTools in turn (Ctrl Z between operations)

I can confirm the described behaviour, however this is to be expected (at least regarding to what the authors documentation says):

From the doc at http://wiki.blender.org/index.php/Extensions:2.6/Py/Scripts/Modeling/LoopTools
There are two valid input methods for the curve tool. The first is to select 2 or more vertices on the same loop. You can do this for multiple loops simultaneously to save time. The second method is to select one or more entire loops. If a full loop is selected, the curve tool won't operate on that loop, but on all loops perpendicular to it and use the vertices on the selected loop(s) as control points.

regarding the second issue mentioned (the one that “Python: VIEW3D_MT_edit_mesh_looptools” appears in the menu):
I can confirm that, too. This seems to be happening when you hold down "W" [to bring up specials]. If you hold it down longer (not just quick press) then looptools submenu is kind of blocked (I guess because "specials" menu is constantly redrawn? - just stab in the dark here...)
