[racket] Scribble "seclink" breaking PLaneT and local documentation cache?

A servlet for the PLaneT site seems broken, and I think that a use of 
Scribble "seclink" in a PLaneT package might be breaking both this and 
my local documentation cache.

The documentation for a PLaneT package contains a link to a manual, like:

@seclink["top" #:doc '(lib "scribblings/scribble/scribble.scrbl")]{Scribble}

When clicking the "doc" link on the PLaneT site, this link becomes to:

http://planet.racket-lang.org/servlets/doc-search.rkt?tag=KCgy[[...long 
string...]]

but that URL results in an error: "Servlet didn't load.".

For example, see the "Scribble" link near top of:
http://planet.racket-lang.org/package-source/neil/scribble-emacs.plt/1/2/planet-docs/scribble-emacs/index.html

I notice that, although my "~/.racket" PLaneT cache shows the 
"index.html" for this version of the package was correctly generated 
with a link to 
"file:///usr/local/racket-5.0.2/share/racket/doc/scribble/index.html", 
my "~/.racket/5.0.2/doc/index.html" contains a link to the previous 
version of the PLaneT package.  Likewise, my documentation search index 
seems to have the previous version of the package, not this one.
