Hi,

Following up on an earlier thread on this list I tried to get rid of some more 
of the flicker occuring when you switch to another directory. The 
accompanying patch solves the problem that newIconSize starts a preview job 
which is immediately stopped again in mimeTypeDeterminationFinished. When the 
preview job is stopped the view is updated.

The best way to prevent this preview job from starting we can check whether 
the current icon size is already the correct one and if so, do nothing.
