Description

Method due_before in app/models/issue.rb can return nil.

app/views/gantt.rhtml doesn't handle this case correctly, instead exiting with the following error:

ActionView::TemplateError (undefined method `<=' for nil:NilClass) on line #184 of issues/gantt.rhtml

This can happen if an issue has a due_date of 0000-00-00 and no fixed_version.

Environment information:

Database Version         mysql  Ver 14.12 Distrib 5.0.67, for suse-linux-gnu (x86_64) using readline 5.2
Ruby version             1.8.7 (x86_64-linux)
Rails version            2.1.2

Error log entry:
