wrong number of arguments exception in ruby 1.9

[brightcode]

When em-dns is used with ruby 1.9 the following exception occurs:

/opt/local/lib/ruby1.9/gems/1.9.1/gems/eventmachine-0.12.11/lib/em/deferrable.rb:148:in call': wrong number of arguments (1 for 0) (ArgumentError) from /opt/local/lib/ruby1.9/gems/1.9.1/gems/eventmachine-0.12.11/lib/em/deferrable.rb:148:inset_deferred_status'

In ruby 1.8 the same code works fine. Maybe this is a problem because of more strict checking of Proc calling semantics?
