Additional testing showed: this problem seams to appear randomly when selecting/deselecting an image in the datamanager when statistics view is active.
Could not be reproduced in Windows, although this might just be coincidence.

Analyzed problem: the javascript is for some reason duplicated when the mitk window is resized. This causes the script to run two (or more depending on number of previous resizes) times, causing random crashes. We assume.

I recognized there is a memory leak in the QmitkHistogramJSWidget, which is probably a bug of the Qt Web Kit.
