http://en.wikipedia.org/w/api.php?action=none results in a text error message:
unknown_action: Unrecognised value for parameter 'action'
To be consistent with the treatment of other errors, it really should return a formatted response (in XML, or JSON, or whatever format has been selected) with an "error" attribute.
Yes, it definitely should. I'm having a really hard time trying to diagnose this bug -- the code is clearly trying to produce a formatted message, but not succeeding for reasons unknown to me. Hopefully Yuri can figure it out better than I can :) Changing severity to "normal"--when a user requests an xml document and doesn't get one back, even if he specified an invalid parameter (or possibly a parameter that will be implemented in later versions, but hasn't been yet), that's a real problem, not a request for a trivial enhancement.
Fixed in r32824.
