Redmine

When using IssuesController.send(:include, ...) from a self-written plugin I get this error at Redmine startup:

[...]/vendor/rails/activesupport/lib/active_support/dependencies.rb:276:in `load_missing_constant': uninitialized constant Redmine::Export::PDF::FPDF (NameError)
from [...]/vendor/rails/activesupport/lib/active_support/dependencies.rb:468:in `const_missing'
from [...]/lib/redmine/export/pdf.rb:25

The solution is to require 'rfpdf/fpdf' in /lib/redmine/export/pdf.rb:
