Using the gem roo-xls I encountered an issue while opening an excel file. I saw it came from the spreadsheet gem. From my understanding the problem comes from a missing format in the excel file even though this file is valid and the code was not handling this missing format properly. I wrote a test and a fix for this issue. I'm not very familiar with the gem so tell me if you see some corrections to make.
