Summary: "g_timer_continue: assertion 'timer->active == FALSE'
failed" in gst_download_buffer_wait_for_data()
Product: WebKit

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):
