Hi Stamatis,

Regarding this errorless crash (not the JPEG2000 problem already analyzed
by Stephan), you could try launching Fiji from the console, and seeing if a
crash report gets printed there.

In Terminal:
/Applications/Fiji.app/Contents/MacOS/ImageJ-macosx

Then create the new image and see if anything is printed to the console.

And if you are feeling tech-savvy, see also:

Best place to report that bug is:
