Roderick Colenbrander and I were talking about the severity levels on irc the other day. We tried to outline the existing severity process that seems to be in use (not what is neccesarily listed in bugzilla) and came up with the following levels of bug severity:
* normal * major (release level, e.g. dib engine, 64 bit support, usb, etc) * blocker (compile failure, severe wine crash, system crash due to triggering driver bugs)
As far as I can see that's what the current usage of serverity is in bugzilla.
Other thoughts during our discussion were that perhaps assignee should be the one that can change the severity rather than reporter.
