see the comment from upstream. the crash with empty CSV file was fixed in Gnumeric 1.7.1. for the other crashes, it should be checked as well whether 1.7.1 fixes them. so at least part of this bug will be fixed by upgrading the gnumeric in ubuntu from 1.7.0 to 1.7.1. -- ssindex crashes https://launchpad.net/bugs/63297
