Bug 788191 reported that the tarballs originally shipped with the release worked only with Guile-2.0. This turned out to be due to an error in SWIG that's in the version on Fedora 25 which I used to create those tarballs. I've re-spun the tarballs and the reporter of the bug has tested that they are now correct. The re-spun tarballs also include src/optional/python-bindings/__init__.py, reported as missing by another user. The sha256 hashes for the re-spun tarballs are: 68730bcfcead7485011eb43d3b2c5df032c714571c81f9a15d33d8494fc4249d gnucash-2.6.18-1.tar.bz2 f66e9e05c332182bd7aa23f9717d4bc32bcfaf2a1eb3a94287c88aeaa7e5894e gnucash-2.6.18-1.tar.gz Note the -1 suffix.
