Shape Extruder Bug

[Britfox]

Hi,

The Shape Extruder isn't working correctly with the last manifoldlab version of Wings3d (Wings 3D 1.5.2.2014-03-17---19-58.mlab)

Nothing appear at the preview and no object is created after clicking OK.

The console window:

wpc_shape_extruder:command/3: bad return value: {'EXIT',
{badarith,
[{wpc_shape_extruder,
make_ngon,6},
{wpc_shape_extruder,
make_ngon,6},
{wpc_shape_extruder,
generate_frustoms,7},
{wpc_shape_extruder,
make_shape,17},
{wpc_shape_extruder,
command,2},
{wings_develop,
time_command,2},
{wings_plugin,command,3},
{wings,raw_command_1,3}]}}
wpc_shape_extruder:command/3: bad return value: {'EXIT',
