Comment 35 for bug 1203406

I think it should be reopened again.

The problem is still there, for almost all versions of nemo currently out there.

The reason why it seemed resolved many times but one could not point out a certain change that resolved it is simple: The cause seems to be out-of-control thumbnailing. If, at some point, the problematic files are thumbnailed or have failed to being so gracefully, cpu and memory usage may drop (or not occur again after restart or reopening of the suspect folder). So the problem may easily seem to fix itself.

This mostly happens when many folders containing images are browsed (thumbnailing a certain won't stop until its done) but also for bad image files, where the thumbnailer is repeatadly invoked on the same file. I think the thumbnailing threads and their data stacks up then and whe experience unlimited cpu and memory usage.
