concat, nil.<< and Rails 2.3.0RC1

When moving to Rails 2.3.0RC1 I get an error with concat!? I can't figure it out. See the dump below:

ActionView::TemplateError (You have a nil object when you didn't expect it! You might have expected an instance of Array. The error occurred while evaluating nil.<<) on line #158 of app/views/places/show.html.erb: 158: <div class="dottedSeparator"></div> 159: <h3><%= "What do you think about '%s'?" / @place %></h3> 160: <% end -%> 161: <% form_for([@place, @review = Review.new]) do |f| %>

    actionpack (2.3.0) lib/action_view/helpers/text_helper.rb:32:in `concat'     actionpack (2.3.0) lib/action_view/helpers/form_helper.rb:252:in `form_for'     app/views/places/show.html.erb:158

It seems to be something with form_for and blocks or something?! It does NOT appear in Rails 2.2.2 however :S

Any help is greatly appreciated!

What's this supposed to be? Is that / supposed to be % (for String#%)?

160: <% end -%> 161: <% form_for([@place, @review = Review.new]) do |f| %>

Hmm.. might be something that / .. It comes from deprecated Globalize (v1) that uses the "blabla %s blabla" / 'something' to translate strings..

Any other ideas?

OK, so Globalize defines a String#/ is it possible that it is not finding a translation for the "blabla" and thus using a nil internally?

I've overwritten the method to NOT return nil in any case. However the error seems not to be in those calls. It's more in blocks or something. See below:

Showing app/views/layouts/_header.html.erb where line #4 raised:

You have a nil object when you didn't expect it! You might have expected an instance of Array. The error occurred while evaluating nil.<<

Extracted source (around line #4):

1: <div id="innerHeader"> 2: <div id="innerLogo"></div> 3: <div id="search" class="overflow"> 4: <% form_tag(search_places_path, :method => :get) do -%> 5: <% with_options(:scope => [:form, :search_place]) do |i| -%> 6: <div class="left"> 7: <div class="left halfMarginRight">

I found it.. it was Erubis that doesn't work with Rails 2.2 and 2.3.
