ladspa-swh-plugins-0.4.15-26.fc23 has been submitted as an update to Fedora 23. https://bodhi.fedoraproject.org/updates/FEDORA-2016-0a86470824
As the previous maintainer, I took the liberty to push the fix.
The packaged version of this software seems quite old, from 2007. The current maintainer could consider contacting upstream and ask about the stability of their git, which is actively maintained. The last time I talked to them (4-5 years ago?), they advised me not to package the git as it was unstable, but things might have changed since.
Thank you for all the patches.
