"can't modify frozen object" about meta-tags

[kpumuk]

Could you show an example on how to reproduce this error? I've tried a few variations and can't get it failing:

  @view.title('someTitle'.freeze)
  @view.display_meta_tags(:site => 'someSite').should == '<title>someSite | someTitle</title>'

  @view.title(['someTitle'.freeze].freeze)
  @view.display_meta_tags(:site => 'someSite').should == '<title>someSite | someTitle</title>'

It is only happening in production mode, and only for some pages. We couldn't figure out what triggers this. The backtrace shows that the error occurs on the line with .map inside normalize title. Maybe rails does some caching for strip_tags or h and freezes the resulting string?

Can you somehow test in production? Maybe with some tags and unescaped html entities in the title.

Added frozen strings in production everywhere. No exceptions. Could you help me to find the problem?

Sorry, I have no idea what to do. Maybe it's one of the other gems or plugins we are using.
