Here is a possible solution with ruby debugger.
The symptoms are: IDE try to connect to debugger, wait 10 seconds and breaks.
The environment is:
- Ubuntu 9.04
- ruby 1.8.6 (2009-06-08 patchlevel 369) [i686-linux] (compiled from sources)
- Rails 2.2.2
Debug gems is:
- Latest ruby-debug-base 0.10.x
- Latest ruby-debug-ide 0.4.6
Looks, that something is broken in this gems. Inspiried by solution from NetBeans
you may try old gems:
It works fine with RubyMine.
