> Issue Type: Bug
> Components: Infrastructure
> Affects Versions: 0.11
> Environment: CentOS 5.3, Erlang R12
> Reporter: Christopher O'Connell

> When an external process returns a value, the couch_log process crashes.
> A couchdb external process is created which returns well formed json as identified below. Whenever the process' url is accessed, couchdb correctly returns the result, however, the couch_log process crashes (log below).
> To replicate this, setup an external process and make a call to it using the mapped url.
> This has been observed on CentOS 5.3 with the most recent version of the 0.10 branch, using a java external process as described below. Similar behavior has also been observed on Ubuntu 9.10 using a php external process (log not included).
> External Program Input: { "path":[],"query":{"hello":"world","abc":123},"verb":"GET" }
> External Program Output: {"headers":{"content-type":"text/plain"},"json":{"hello":"world","abc":123},"code":"200"}
> Couchdb URL: .../_exj?hello=world&abc=123
> Couchdb Response: {"hello":"world","abc":"123"}
> ***** Log *****
