Package: libxkbregistry0 Version: 1.7.0-2 Followup-For: Bug #1153019 Hi,
I hit this on Debian 13 (trixie) on 2026-11-05 with libxkbregistry0 1.7.0-2, libxml2 2.12.7+dfsg+really2.9.14-2.1+deb13u3, gnome-shell 48.7-0+deb13u2 (Wayland). Impact: it was impossible to log in graphically. After entering the password in GDM the screen went black and returned to the greeter (6 times that morning); afterwards the greeter was grey and unresponsive. Only a text console login worked. Trigger: api.met.no (the backend libgweather uses) returned "502 Bad Gateway" as an HTML page. libgweather fed that to libxml2, libxml2 raised a parse error, and the generic error handler that libxkbregistry had installed earlier (with an already freed rxkb_context) was called. So any GNOME user with a weather location configured (Clocks/Weather, or the weather in the top bar calendar) can end up in a login loop whenever the weather service has an outage. This is not something a user can easily diagnose. Kernel log: gnome-shell[...]: general protection fault ... in libxkbregistry.so.0.0.0 Backtrace (shortened, from coredumpctl): #0 libxkbregistry.so.0 (xml error handler, dangling context) #3 __xmlRaiseError (libxml2) #10 xmlParseMemory (libxml2) #11 libgweather-4.so.0 #14 libsoup-3.0.so.0 Workaround: from a text console, clear the weather locations gsettings set org.gnome.shell.weather automatic-location false gsettings set org.gnome.shell.weather locations '[]' gsettings set org.gnome.Weather locations '[]' and restart gdm. This is upstream issue #529, fixed in libxkbcommon 1.8.0 (https://github.com/xkbcommon/libxkbcommon/issues/529, fix in commit a47961b15a2539a417bd6f20570074ec01aadec4). The version in trixie-backports (1.13.1) contains the fix, but trixie itself still ships 1.7.0. Given that an external service outage can lock users out of their desktop, could the fix be backported to trixie via a stable point release?
