[ic] Interchange 5.10 catagories

[kerry]

I noticed that spaces matter in category name on my test setup of IC
Strap 5.10. If you have more than one space between words, the menu
shows error.

I tried to duplicate in the demo, but when trying to edit the category
of an item, error message shows at top, and the function is not completed.

My double space was just a case of moving and editing my old category to
new category that would work better in strap, but was surprised that the
extra space caused a problem.
