Constructor segfaults when http:// is used in URL

This works:

$cb = new Couchbase("184.72.2.230:8091"); // uses the default bucket

This segfaults:

$cb = new Couchbase("http://184.72.2.230:8091"); // uses the default bucket

At least some better message to the user would be nice.

Can we also check this for all of our other libraries? The standard way of doing things used to be to put the full URL on there...and still is for .NET at least.
