client crashes on received message (NOTICE?)

[Dan Finch]

While running a client in F# interactive, the client crashed on what apparently was a notice. Here is the stack trace:

It looks like changing a single `if` to `else if` solves this problem. I'll commit the fix shortly; it will be present in the 0.4.1 release. Thanks for the report.
