It sounds like from Brandon's comment here that bug reports should be submitted directly to Craft Support.
...please contact us directly when you run into bugs such as PHP/MySQL errors. Preferably through the Get Help widget on your Dashboard (which can include a DB backup), or you can email firstname.lastname@example.org.
With that in mind, should bug report-type questions (PHP or MySQL errors), be allowed at all? Or simply closed as off-topic?
