"Loading Rake tasks..." menu item never completes

I have had this problem with RubyMine 3.0.1 and 3.1: the Tools | Loading Rake tasks... menu never completes, and thus I never have a Tools | Rake Tasks... menu.

If I create a new Rails project, I get a clean Tools | Rake Tasks... menu, so it's a problem with the somewhat large Rails project that I work on. What I'd like to know is how to investigate and solve this problem.

From the command line, 'rake -T' works, but emits several DEPRECATION WARNING lines. (This is a Rails 2.3.8 project with several plugins that are causing some deprecation warnings.) There are also a few custom rake tasks in our project that emit multi-line descriptions, causing 'rake -T' to emit more than one line per rake task.

The Rails project with this project is able to run, both with and without the debugger, from within RubyMine. In fact, I haven't noticed any other RubyMine functionality that isn't working in this project.


Thank you.


P.S. Here are the deprecation warning lines:

DEPRECATION WARNING: Rake tasks in vendor/plugins/active_scaffold_list_filters/tasks, vendor/plugins/acts_as_property_driven/tasks, vendor/plugins/db_content/tasks, vendor/plugins/funkytown/tasks, vendor/plugins/funkytown/tasks, vendor/plugins/loopy_multiple_databases/tasks, vendor/plugins/paperclip/tasks, vendor/plugins/rails-iui/tasks, vendor/plugins/selenium-on-rails/tasks, and vendor/plugins/use_db/tasks are deprecated.

P.P.S. Here are some examples of the multi-line descriptions that 'rake -T' emits:

Hi Ed,

Probably our rake task list parser hangs. Could you file a bug report at http://youtrack.jetbrains.net/issues/ruby? Please also attach a couple thread dumps. To get a thread dump you need invoke in console:

$ jstack <pid>

where <pid> - is numeric pid of RubyMine process.
