Redmine

Hello, Everyone!

I have installed Bitnami Redmine Stack 1.4.1 on the clear computer.
When I try to export issues in gantt png view I have some error.
Hear the log:

Processing GanttsController#show to png (for 10.155.13.16 at 2012-04-27 15:15:46) [GET]
  Parameters: {"action"=>"show", "month"=>"4", "controller"=>"gantts", "zoom"=>"2", "project_id"=>"pr1", "format"=>"png", "months"=>"6", "year"=>"2012"}

Magick::ImageMagickError (RegistryKeyLookupFailed `CoderModulesPath' @ module.c/GetMagickModulePath/657):

  app/controllers/gantts_controller.rb:42:in `show'
  config/initializers/mongrel_cluster_with_rails_211_fix.rb:62:in `dispatch_cgi'

Can you help me to say what is it possibly problem?
