If g_get_home_dir() calculated a NULL home directory (due to $HOME being unset and /etc/passwd being inaccessible, for example due to an overly-zealous LSM), it would call g_once_init_leave (&home_dir, NULL), which would emit a critical and fail to leave the GOnce critical section. That meant that the following call to g_get_home_dir() would deadlock in g_once_init_enter(). Fix that by setting the home directory to a made-up value in such cases (which the documentation handily already explicitly allows). Thanks to Simon McVittie for the analysis leading to an easy patch. Signed-off-by: Philip Withnall <withnall@endlessm.com> https://bugzilla.gnome.org/show_bug.cgi?id=773435
