Bug #2689: rdoc gem on 1.9.2 fails for interactive(-i) ri
http://redmine.ruby-lang.org/issues/show/2689

Author: Benoit Daloze
Status: Open, Priority: Normal
Category: core, Target version: 1.9.2
ruby -v: ruby 1.9.2dev (2010-01-27 trunk 26434) [x86_64-darwin10.2.0]

Sorry if this has been already signaled, I didn't see.

So, doing a simple 'ri Fixnum':
~ $> export RI='--no-pager -i'
~ $> ri Fixnum
# Without the gem, all is good
# But with rdoc gem:
~ $> gem install rdoc
Successfully installed rdoc-2.4.3
1 gem installed
Installing ri documentation for rdoc-2.4.3...
Installing RDoc documentation for rdoc-2.4.3...
~ $> which ri
.../ruby-1.9.2-head/bin/ri # It's still the same 'ri'

~ $> ri Fixnum
Updating ri class cache with 1764 classes...

Enter the method name you want to look up.
You can use tab to autocomplete.
Enter a blank line to exit.

>> 
# Where is my documentation ?
# Back to normal if I uninstall rdoc, with its binaries

That's quite an annoying bug, not so easy to track.
