reduce_overflow_error when added a public key in dev.bm

I've added a public key for a user I'm using (test1) through the webapp. Now whenever I tried to retrieve this data, I get the following error:

$ curl -k --netrc-file ../netrc -X GET "http://localhost:6666/users/_design/User/_view/by_login/?key=\"test1\"&include_docs=true&reduce=false&reduce_limit=false"
{"error":"reduce_overflow_error","reason":"Reduce output must shrink more rapidly: Current output: '[\"0-----BEGIN PGP PUBLIC KEY BLOCK-----\\u000d\\u000aVersion: GnuPG v1.4.11 (GNU/Linux)\\u000d\\u000aCom'... (first 100 of 2141 bytes)"}

Removing reduce_limit or chaging include_docs doesn't change the error result.

I'm assigning this to Platform since Jessi confirms this doesn't happen in her local intallation, but I'm not really sure where's the issue.
