passing an argument to a library constructor doesn't work anymore with ci 1.7 :(

I tried with a fresh install of ci 1.6.3 and 1.7 , and I can reproduce this problem. (It works with ci 1.6.3 but not with 1.7)

I solved the problem passing an array, instead of a single variable.
So this is a new behaviour.
Maybe I was "lucky" that it worked with 1.6.3, but the doc doesn't say that the params MUST be an array.
