[Reply from Eric Hodel]

Looks like qri is using RDoc 1.0.1, which is shipped with ruby.  RDoc
2's on-disk YAML format is not backwards compatible with RDoc 1.  RDoc
2 can read RDoc 1's format due to some use of regular expressions.
fast-ri would need to be updated to read the RDoc 2 classes.


So, if Eric is right, then fastri needs to be updated to understand the
current yaml format generated by current versions
of rdoc...

The problem for TextMate / RubyMate is that its Help uses qri, which is
fastri. In fact, that is how I discovered the problem. I installed the new
rdoc, regenerated my help files, and found that Help in RubyMate had stopped
working, with the above error.

Just letting y'all know... m.
