How to get Rails’ script/breakpointer work in RDT 0.7 in Eclipse 3.1.2?

I’m new to Rails and have gotten breakpointer working in a csh on Fedora  
Core 4. Also, the RDT setup works for breakpoints set in straight Ruby  
code. I’m trying  
[Setting up a Rails Development Environment on Windows Using Eclipse | New Auburn Personal Computer Services LLC](http://www.napcs.com/howto/railsonwindows.html#setupbreakpointer). But a  
breakpoint set in Eclipse doesn’t get hit at all. Fine! I place a  
breakpoint() call in my Rails code. It gets hit alright… but the  
server exits right away. It won’t let me get into irb.

— From Eclipse Console —  
Tries to connect will be made every 2 seconds…  
Executing break point “Let’s break for a while :)” at  
./script/…/config/…/app/controllers/store\_controller.rb:28 in  
`display\_cart’  
Server exited. Closing connection…

## No connection to breakpoint service at druby://localhost:42531 (DRb::DRbConnError)

What could I be doing wrong? Or any newie friendly & free RoR debuggers  
out there? Any advice will be greatly appreciated!

Apparently, script/breakpointer is a wrong place to start. I got it  
going a little by debugging script/server. But this combo of RDT  
(0.7.0), Eclipse (3.1.2), Ruby (1.8.4) and Rails (1.0) on Fedora Core 4  
gets a segment fault when resuming a breakpoint. Anybody got a GUI  
debugger working on Liunx?
