Finally I could reproduce the bug in a freshly created Rails 3 application, requiring one by one the gems I used in my first application. The bug occurs when both twitter and sg-ruby gems are required from Gemfile. If only one of both is required, the bug disappears. Reading through the code of both gems, I could not figure out how the bug appears. So to avoid the bug I just switched from the twitter gem to the grackle gem.
