Globalize Currency Negative Value Error

I’ve got the Globalize-1.1 release installed and have been using the
globalize plugin for a month or so now. My base locale is en-US, Ruby
1.8.4 (2005-12-24), Rails 1.1.2. Here’s the problem taken from
./script/console:

Loading development environment.

Globalize::Currency.new("-340")
=> #<Globalize::Currency:0x2337478 @cents=-340>

Globalize::Currency.new("-340").to_s
=> “-4.60”

Globalize::Currency.new(“340”).to_s
=> “3.40”

Globalize::Currency.new("-340").to_s
=> “-4.60”

Locale.set(“en-US”)
=> …

Globalize::Currency.new("-340").format
=> “-$4.60”

Globalize::Currency.new(“340”).format
=> “$3.40”

Any insights and/or patches would be greatly appreciated.
