Description

When I migrate from my Trac 0.12 database using sqlite3. I encounter this error :

Not knowing much about ruby I have some problems finding where it comes from

It looks like you're not using the migration script (lib/tasks/migrate_from_trac.rake) provided with 1.0.3.
Anything else to mention?

I am using the migration script from the 1.0.3 version.

The problem seems to be that function Time.fake() has problem to handle when the given input is nil.

  class ::Time
    class << self
      alias :real_now :now
      def now
        real_now - @fake_diff.to_i
      end
      def fake(time)
        @fake_diff = real_now - time
        res = yield
        @fake_diff = 0
       res
      end
    end
  end

To solve that issue I modified this function in such way :

  class ::Time
    class << self
      alias :real_now :now
      def now
        real_now - @fake_diff.to_i
      end
      def fake(time)
        time = 0 if time.nil?
        @fake_diff = real_now - time
        res = yield
        @fake_diff = 0
       res
      end
    end
  end

The migration works perfectly nows. I have a few other trac to migrate, I'll try this modification and if it work I'll add a patch file.
