After enabling fatal-criticals for glib (see bug #276819) I started to observed some crashes with the following error message preceding it: "(WPEWebProcess:2): GLib-CRITICAL **: 09:13:26.792: g_timer_continue: assertion 'timer->active == FALSE' failed" This is the same assertion error as encountered in bug #132262. The backtrace is (not sure if the additional data from "bt full" vs "bt" is helpful as everything is optimized away): #0 _g_log_abort (breakpoint=<optimized out>) at ../glib/gmessages.c:426
