2.2.5 release api-1.1 500 errors

[Konstantin Ryabitsev]

Hello:

After the 2.2.2->2.2.5 upgrade, we seem to be getting lots of /api/1.1/ errors
for PATCH calls:

    PATCH /api/1.1/patches/{id}/

switching to /api/1.2/ seems to fix it, but requires other client app fixes
for API incompatibility.

Some of the others returning 500 errors are:

    GET /api/patches/{msgid}/comments/ 

I'd be happy to provide tracebacks if I can figure out how to get them.
