calibre 2.67 on OSX 10.11.5/10.11.6 content server failing

I noticed recently that the content server isn't working correctly; I think this started coincident with the new version I installed.

When I connect with Calibre Companion, I'm not able to retrieve any of the list of books.

Looking at the Error log: inside of the preferences panel, I see this:

[11/Sep/2016:00:02:03] HTTP Traceback (most recent call last):

UnboundLocalError: local variable 'mi' referenced before assignment

which appears suspicious.. Taking a quick look inside the application wrapper didn't reveal anything specific due to the compiled python files vs. source code.

I tried applying the pending OSX update from 10.11.5 to 10.11.6 to see if that (or a reboot) might help, but it doesn't appear to.

This seems specific to using Calibre Companion... in the Access Log, I see:

10.200.253.24 - - [11/Sep/2016:00:01:55] "GET / HTTP/1.1" 200 6461 "" "Apache-HttpClient/UNAVAILABLE (java 1.5)"
10.200.253.24 - - [11/Sep/2016:00:01:55] "GET /opds HTTP/1.1" 200 3715 "" "Apache-HttpClient/UNAVAILABLE (java 1.5)"
10.200.253.24 - - [11/Sep/2016:00:02:03] "GET /opds/navcatalog/4f6e6577657374 HTTP/1.1" 500 805 "" "Apache-HttpClient/UNAVAILABLE (java 1.5)"

Now, I'm not sure if there is an issue with Calibre Companion making unwarranted assumptions, but I think that the cherrypi web server shouldn't be throwing an error like the one in the log when handed a bogus URL..

Just pointing a web browser to the content server directly seems to yield the expected result.

This is a bug (regression) in calibre 2.67 and has nothing specific to do with CC. Any OPDS client will trip over the same problem.

Thanks for the pointer to the bug report, and sorry that I missed searching over there first.
