Created attachment 312977 [details] backtrace. A highlighted copy is here https://paste.gnome.org/pj4ezlixh :) It should be the same as the attached file. Here's another one that would be good to look at. The HLS code has always been racy but I thought we fixed this previously... looks like there are still more problems. The backtrace looks similar to the last bug Carlos Garcia fixed. (Do you have a link, Carlos?) This is 2.16.3 with the patch for bug 170003 and this patch https://git.archlinux.org/svntogit/packages.git/plain/trunk/icu59.patch?h=packages/webkit2gtk I'm not seeing the seeking lockup anymore so I believe it is a different isse.

Just to be clear, I have applied the patch for bug 170003 and it fixed the seeking issue. However, I now get crashes on live youtube streams. Regular streams no longer crash. This looks like a different bug. No, not bug #170003, it was an issue with HLS and WebKitWebSrc. FYI this is probably a tricky problem regarding thread safety and GMainContext dispatches [1], which are very easy to screw up if you don't read the instructions very carefully. I'm still not comfortable with them myself. So don't feel bad if you can't figure it out. But if you can, then that's excellent. I'm sure Carlos Garcia will post some advice tomorrow, since he's worked on this issue before. I'll also CC our GStreamer experts, Calvaris and Enrique. [1] https://developer.gnome.org/programming-guidelines/stable/main-contexts.html.en This is actually a duplicate of #152043. I think it's time to get rid of the weak ptr in the main thread notifier. *** This bug has been marked as a duplicate of bug 152043 *** Thanks Michael & Carlos. Just for OP's reference, this isn't the only problem with YT live streams, I'm looking at https://bugs.webkit.org/show_bug.cgi?id=173463 as well. I tried the patch in bug 152043. It still crashed. (In reply to Hussam Al-Tayeb from comment #10) > I tried the patch in bug 152043. It still crashed. It can't be the same bt, so we need a new one Just to rule out any mistakes on my side, the patch didn't actually apply correctly to 2.16.3 and I had to re-diff it. https://paste.gnome.org/px2meutl6 is this correct?

Yes, that looks good. Thanks. I'm doing a debug build now. I forgot to -DCMAKE_BUILD_TYPE=Debug when I tried the patch. I'm facing technical difficulties.
epiphany won't start with the debug build now
