The story is not limited to proprietary formats. I found a 10 year old Gnucash file generated with gnucash-1.6, but today's Gnucash does not know how to read that file.
In the end, i installed debian sarge in a chroot (thanks archive.debian.org!) so I could run gnucash 1.8 without building the 20 little dependencies.
