No math with distance variable

[GoogleCodeExporter]

What steps will reproduce the problem?
1.local d = Wherigo.Distance(10, 'ft')
2.local z = d * 2

What is the expected output? What do you see instead?
Works with the Wherigo-Builder. Crashes on an Android-Phone. Comfirmed with the 
OpenWig-Desktop-version.

Workaround:
1. local d = Wherigo.Distance(10, 'ft')
2. local dn = d:GetValue('ft') -- or d:GetValue 'ft' NOT!! d.GetValue('ft')
3. local z = Wherigo.Distance(dn * 2, 'ft')
