QS60Style assert fails to detect an index failure
QS60Style assert fails to detect an index failure

QS60Style asserts that a given index is correct when setting theme
colors. Unfortunately it uses less-and-equal-to operator ('<='), which
is incorrect. It should use less-than ('<')operator, otherwise the
assert fails when index is equal to number of items in the color
table.
