Hi Charlie,

Yes, but this is the first time I've seen it, so I don't know what
happened to your previous submission.

We've duplicated the problem using the files you made available, and
it looks like a bug in how ncdump displays multidimensional character 
arrays that have more than one unlimited dimension.  We hope to have
a fix soon.

Thanks for being persistent about reporting the bug.
