My mistake, you both are right.

The long term goal is to understand how MotionBlur works, create a working
testcase and write a description in manual. Then we can understand why
camera is needed for the plugin. After that it is possible to find
workaround for the problem how to use it in Render Effect case. All other
plugins can be used through 'Render Effect' (I think so), so should
Another (short term) possibility is to creat a plugin propery for example
'is_interactive'. If this property is non zero, the plugin is not shown in
Render Effect menu.
The question is: how behaves MotionBlur during background rendering, batch
rendering and in renderfarm. Do we have more exeptional plugins?
As pointed out by Igor we have similar problem with multichannel and
singlechannel plugins - misuse resulting crashe is possible.
