nested query params throws quri.error exception with Woo

[eternal-turtles]

When running Hunchentoot, the association list is returned properly. However, when I switch the server for Woo, I hit an exception. I am running SBCL on OS X.

So: /foo?bar=hello returns ((bar . hello)) without problem, but /foo?foo[bar]=hello throws an exception:

Callback Error: the message-complete callback failed

Callback Error: the message-complete callback failed
  URI "/foo?foo[bar]=hello" contains an illegal character #\[ at position 13.
   [Condition of type FAST-HTTP.ERROR:CB-MESSAGE-COMPLETE]

[fukamachi]

What happens if you URL-encode the query keys?

[eternal-turtles]

Apologies for the long delay -- I haven't actually been able to reproduce this again, so I think this may have been user-error on my part. Closing the issue.
