"Nullable object" exception

Dec 14, 2009 at 9:24 PM

We use DotNetZip 1.8 in one of our products.  A customer was trying to add an empty directory to a zip file.  When the Save method was called, it threw a "nullable object must have a value" IO exception.  We were not able to reproduce this problem.  When we zipped an empty directory, DotNetZip produced an empty zip file, as expected.  Has anyone seen anything like this?
