Created attachment 372891 [details] thread info and thread traceback I'm using liferea which uses webkit to display web content. For several weeks I've noticed the stability of webkit has declined. It frequently locks up and I have to restart the webkit web process. I've started attaching gdb to it instead of killing it and I found the main thread blocked in gst_adaptive_demux_change_state() blocking on a mutex. The other thread is source:src and it is in timedWait() from libjavascriptcoregkt. There seems to be several different instances where it hangs in a deadlock between two threads. This url is example: https://twitter.com/TIME/status/1142178303656288256/video/1 I've attached the traceback and thread info for loading the url. I can reproduce it easily.
