Exception when opening LZW-TIFFs as stack

Dominik Geisel
Hello!

when I open some LZW-compressed TIFF-files as a stack, I get the following
exception (not a once but after opening some 3-5 images):


java.lang.ArrayIndexOutOfBoundsException

Anyone knows what could be the problem?

Does it happen consistently with certain TIFF files? Or only
intermittently after loading a few files? Either way, if you can
identify a procedure that causes the exception, and post the TIFF files
you used somewhere online, it would be very helpful for diagnosing this
problem.
