[Bf-taskforce25] Bug report

[Ton Roosendaal]

Hi Jingyuan,

Thanks, fix goes to svn now.

It's one of the leftovers of not having globals anymore; the preview 
icon for render result used to be retrieved using the G.scene, which 
has been depricated.

I've made both image code save for missing iuser pointer, as made icon 
renders pass on a valid 'image user' as well.
