Redmine

Hello,

I have been trying redmine, but apparently a lot of pages (project activity, issue details, ...) are breaking because of an issue in ruby1.8.7 (not a redmine issue).

Over the past couple of days, I have been checking out the fora, bugs, patches, and so on - ao. this came in as the solution pretty much everywhere:
http://www.redmine.org/issues/show/1609

Basically, a patch to revert text_helper.rb in the ruby folder to the 1.8.6 version (please correct me if I'm wrong).

A lot of people reported this patch to be effective, and that it got Redmine up and running again.
However, I'm sad to say - this is not the case here. I patched the file, restarted apache, and still get the same error.

If anybody here has more information about this, I'd be very happy to hear it.
I can provide more information if needed - running Redmine on a local development server (Debian), and I'd prefer not to downgrade to 1.8.6, if possible.

Output error:
undefined method `length' for #<Enumerable::Enumerator:0xb6ecd130> for page activity for a project
undefined method `length' for #<Enumerable::Enumerator:0xb6ef6864> for page timelog (details) for a project

I'm pretty sure the same issue is creating havoc on these pages - which is precisely what the patch advertises to fix.
Maybe I'm being n00b here, but apart from patching the text_helper.rb file and restarting apache, is there anything else I'd need to do?

Any comments and/or help is much appreciated.

Greetings,
Frank
