Please binNMU xz-utils rdeps for ABI change
Upstream made some interface changes to liblzma. I don’t think any of
the packages currently in Debian are affected by the API change, but
the ABI change is real and necessitated a soname bump.
Could you schedule binNMUs to rebuild against the new version?
nmu lsb-rpm_4.7.1-11 . ALL . -m 'Rebuild against liblzma1.'
nmu mupen64plus_1.5+dfsg1-7 . ALL . -m 'Rebuild against liblzma1.'
dw lsb-rpm_4.7.1-11 mupen64plus_1.5+dfsg1-7 . kfreebsd-i386 . -m 'liblzma1'
