open density calibrated NIH-images in ImageJ

ard
I've got series of density calibrated images, once upon a time saved
in NIH-Image. ImageJ gives me a null pointer exception*) when I open
these files. When opened the files under classic in NIH-Image, all
goes well. Removing the calibration in NIH-Image and then saving the
file allows opening in ImageJ. Obviously, the image is no longer
calibrated.

Is there a way to open calibrated NIH-Image images into ImageJ
without losing the calibration? The docs on imagej.sourceforge.net
suggest that it should be possible since v1.21: "Density calibration
information in NIH Image TIFF files is now decoded. (a)".
The only thing I recently changed in my system (MacOS X) is the
installation of "Java for Mac OS X 10.4, Release 5" (5.0)
