weka segmentation seems to have broken

[Aryeh Weiss]

When I run the advanced weka segmentation plugin, I get an exception,
which I appended after my .signature .

This is on a mac OSX (10.6.8)
Fiji distribution, with ij.jar 1.47b10
(also happened with 1.47b8 and 1.47a)

Has anyone else seen this? Has a something changed recently?

It works for me. Have you updated Fiji?

Would you mind using Fiji's Help>Report a bug feature? It would help us
identify the .jar file versions you have.

Thanks,
