I've run the tests on Ubuntu 10.10 and 11.10.

I'm honestly not sure why the tests do not pass on your machine, but essentially, the issue is that the pack method at /lib/spreadsheet/excel/writer/worksheet.rb:760 does not accept nil values.

I've run into this issue elsewhere as well, but got around it by adding additional logic to avoid calling the method that was crashing for that particular case.
