Rendering /var/lib/redmine/public/500.html (500 Internal Server Error)

It seems, that something goes wrong with the trac importer.
I created another project to test the functionality and there all works.

Any news? At least a work around would be nice...

The problem is that trac import failed to handle mysql dates so all dates in the database are '0000-00-00 00:00:00'. Redmine treats such date as nil so an error occurs while sorting (sorting patch was not enough).
So I had to replace all 0 dates to some valid date (i.e. 1970 00:00:00).

Trac 0.12 use unix time with microseconds. Here's a fix to migrate_from_trac.rake:

      class ::Time
        class << self
          alias :real_at :at
          alias :real_now :now
          # Fixing import for trac 0.12
          def at(time)
            d = nil
            if time > 10000000000 then
                d = real_at(time / 1000000, time % 1000000)
            else
                d = real_at(time) 
            end
            d
          end
          def now
            real_now - @fake_diff.to_i
          end
          def fake(time)
            # Adding nil argument handling
            time = 0 if time.nil?
            @fake_diff = real_now - time
            res = yield
            @fake_diff = 0
           res
          end
        end
      end

Please include it in the latest trunk. Thanks.

Hey,

Sorry I can't answer. I haven't tried it again for a long time.

Can you try this patch:
