rake aborted! undefined method `text_area' for class `ActionView::Base'

I am very confused by a sudden problem with running rake tasks:

softwareclick:/myapp/current# rake my_task --trace
(in /myapp/releases/20100621162444)
** Invoke my_task (first_time)
** Invoke environment (first_time)
** Execute environment
rake aborted!

I run a passenger/nginx app on debian with ruby 1.8.5 and the following gems installed:

actionmailer (2.3.8)
actionpack (2.3.8)
activerecord (2.3.8)
activeresource (2.3.8)
activesupport (2.3.8)
ancestry (1.2.0)
chronic (0.2.3)
fastthread (1.0.7)
git (1.2.5)
haml (3.0.12)
hoe (2.6.1)
json (1.4.3)
json_pure (1.4.3)
lipsiadmin (5.1.2)
nokogiri (1.4.2)
passenger (2.2.14)
postgres (0.7.9.2008.01.28)
rack (1.2.1, 1.0.1, 1.0.0)
rails (2.3.8)
rake (0.8.7)
RedCloth (4.2.3)
rubyforge (2.0.4)
sitemap_generator (0.3.3)
texticle (1.0.2)
version (0.9.2)
whenever (0.4.2)

Due to the --trace I think it's something between lipsiadmin and active_support, but I simply can't figure out how to go forward.

Does anyone have an idea?

Thanks for your help,

Val

What does the rake task look like? Are you including a dependency on :environment?

Do any other rake tasks work?

Remember that rake does NOT start up the rails stack unless your task has an :environment dependency.

UPDATED: My further suggestion, in the comments, was the right answer:

Gems, and plugins, can have dependencies on each other that require specific load order. So the solution is to remove gems/plugins to find which one is causing the problem. Then add it back into the system and choose the load order explicitly.
