Same problem here on Edgy x86, with 1.7.0-1ubuntu4 . gnumeric fails to open XLS files, but gnumeric-gtk works just fine.
Dunno if either of the following are relevant but FYI: 1. I'm a Kubuntu user. 2. Installing gnumeric-gtk pulled in pxlib1, while plain gnumeric did not. -- amd64 version of gnumeric does not read or write excel format https://launchpad.net/bugs/83568 -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
