This should probably be reassigned to some suitable pseudo-package, but I don't know which one (general? release.debian.org? ...) so for now I'm leaving it with librsvg. This is also preventing at least git from migrating to testing, if I'm reading correctly. cc'ing the release team for visibility. git has failed the majority of its builds on mips64el since 2023-12-31. Doing a spot check on the failing build logs, I see: > fatal: read error: Bad address > fatal: error in sideband demultiplexer or > fatal: read error: Bad address > fatal: early EOF in most of them. The fact that git basically works on every other architecture would seem to point to this being something mips64el-specific, either specific to these particular buildds (which I know we have had problems with in the past) or a more general architecture/kernel/toolchain problem. wings3d also has a mips64el-specific build failure with a suspiciously similar message: > signal-dispatcher thread got unexpected error: efault (14) I don't think it's fair to expect the maintainers of these particular packages to be responsible for the health of mips64el. smcv
