During reading latest revisions from SVN repository we encounter issue with too long comment:

ActiveRecord::StatementInvalid (Mysql2::Error: Data too long for column 'comments' at row 1: INSERT INTO `changesets` (`comments`, `commit_date`, `committed_on`, `committer`, `repository_id`, `revision`, `scmid`, `user_id`) VALUES ('..Here was looong comment..', '2014-02-07 15:10:46', '2014-02-07 15:10:46', 'pbaravik', 3, '30390', NULL, NULL)):
  app/models/repository/subversion.rb:72:in `block (2 levels) in fetch_changesets'
  app/models/repository/subversion.rb:71:in `block in fetch_changesets'
  app/models/repository/subversion.rb:70:in `reverse_each'
  app/models/repository/subversion.rb:70:in `fetch_changesets'
  app/controllers/repositories_controller.rb:114:in `show'

Log message was really long, something about 100K (autogenerated after merge). After trimming this log message error disappears.

Is it possible trim too long comments before insert them in database?
