"Bad system call." parsing playlist files in Flatpak
Using the totem Flatpak from totem!154 (merged), I get a crash in the extract. I don't know whether the problem is the nightly platform, glib, Flatpak's seccomp or something else.
Core was generated by `/app/libexec/tracker-extract-3 --domain-ontology /app/share/tracker3/domain-ont'.
Program terminated with signal SIGSYS, Bad system call.
warning: Unexpected size of section `.reg-xstate/16' in core file.
