I managed to get the edgy version to crash by just moving sheet tabs around. I followed the above procedure, and then continued to move them around randomly. After a handful of moves, gnumeric crashed. Here is the report that Ubuntu generated.
FYI, edgy version is 1.7.0 ** Attachment added: "crash report" http://librarian.launchpad.net/4948178/_usr_bin_gnumeric.1000.crash -- Moving sheet tabs results in wrong order or crash https://launchpad.net/bugs/68827 -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
