** Description changed: + [ Impact ] + There's an infinite recursion in MIME resolution bug which affects processes using gio to resolve certain MIME types. In my case, tracker- miner-fs-3 has been crashing in a loop for weeks due to this issue. + + This affects any program that attempts to resolve a "recursive" MIME + type using glib. I reported the issue to the GLib maintainers here: https://gitlab.gnome.org/GNOME/glib/-/issues/3601 The fix is given here: https://gitlab.gnome.org/GNOME/glib/-/merge_requests/3714 The backport to 2.78 is here: https://gitlab.gnome.org/GNOME/glib/-/merge_requests/3718 - I'm requesting the fix be backported into ubuntu.
